fix: Ensure state persisted to `/var/mail-state` retains correct group (#3011)
* fix: RSPAM ENV should only add to array if ENV enabled

* fix: Correctly match ownership for Postfix content

- `/var/lib/postfix` dir and content is `postfix:postfix`, not `postfix:root`.
- `/var/spool/postfix` is `root:root` not `postfix:root` like it's content.
- Add additional comments, including ownership changes by Postfix to `/var/spool/postfix` when process starts / restarts.

* fix: Ensure correct `chown -R` user and groups applied

These were all fine except for clamav not using the correct clamav group. `fetchmail` group is `nogroup` as per the group set by the debian package.

Additionally formatted the `-eq 1 ]]` content to align on the same columns, and added additional comment about the purpose of this `chown -R` usage so that it's clear what bug / breakage it's attempting to prevent / fix.

* refactor: `misc-stack.sh` conditional handling

The last condition doesn't get triggered at all AFAIK.  Nor does it make sense to make a folder path with `mkdir -p` to symlink to when the container does not have anything to copy over?

- If that was for files, the `mkdir -p` approach seems invalid?
- If it was for a directory that could come up later, it should instead be created in advance? None of the current values for `FILES` seem to hit this path.

Removing as it doesn't seem relevant to current support.

Symlinking was done for each case, I've opted to just perform that after the conditional instead.

Additional inline docs added for additional context.

* chore: Move amavis `chown -R` fix into `misc-stack.sh`

This was handled separately for some reason. It belongs with the other services handling this fix in `misc-stack.sh`.

The `-h` option isn't relevant, when paired with `-R` it has no effect.

* fix: Dockerfile should preserve `clamav` ownership with `COPY --link`

The UID and GID were copied over but would not match `clamav` user and group due to numeric ID mismatch between containers. `--chown=clamav` fixes that.

* chore: Workaround `buildx` bug with separate `chown -R`

Avoids increasing the image weight from this change by leveraging `COPY` in the final stage.

* chore: `COPY --link` from a separate stage instead of relying on scratch

The `scratch` approach wasn't great. A single layer invalidation in the previous stage would result in a new 600MB layer to store.

`make build` with this change seems to barely be affected by such if a change came before copying over the linked stage, although with `buildx` and the `docker-container` driver with `--load` it would take much longer to import and seemed to keep adding storage. Possibly because I was testing with a minimal `buildx` command, that wasn't leveraging proper cache options?

* lint: Appease the linting gods

* chore: Align `misc-stack.sh` paths for `chown -R` operations

Review feedback

* fix: Reduce one extra cache layer copy

No apparent advantage of a `COPY --link` initially in separate stage.

Just `COPY --chown` in the separate stage and `COPY --link` the stage content. 230MB less in build cache used.

* fix: Remove separate ClamAV stage by adding `clamav` user explicitly

Creating the user before the package is installed allows to ensure a fixed numeric ID that we can provide to `--chown` that is compatible with `--link`.

This keeps the build cache minimal for CI, without being anymore complex as a workaround than the separate stage was for the most part.

* chore: Add reference link regarding users to `misc-stack.sh`
