Update kindle on linux documentation

- ActivePython for x86 is gone, but using regular python, at least for the kindle decryption, works.
- The new kindle for pc hangs during wine installation, but the one presented by `winetricks kindle` works.
- The decryption keys must be manually obtained.
- vcrun2008 stops any available version of Kindle from being able to install.

I have only tested these steps for kindle for PC on linux, so these changes may step on some toes. However, it does seem the linux documentation needs updating nonetheless.
