Missing decoders for amavisd

[Fmstrat]

Just fired up a new instance and noticed that amavisd is gong to fail to inspect a number of archives due to the lack of decoders:

At the very lest, 7z and unrar-free should be added as a package to handle common archives, but the best solution would be to ensure each archive format has a decoder. Thanks!

Hi @Fmstrat, you're right. But I'm not sure all these should be enabled.
7z, rar, perhaps doc may be added if you want to submit a PR.
