bug#31283: gnu: Add amule.

[Ludovic Courtès]

Hi,

Applied with the cosmetic changes below.  I took the liberty to remove
the bits about aMule being free software (everything is free software in
Guix), and about it being super-highly-portable (that’s not a primary
concern to Guix users who read the description.)

Thank you,
Ludo’.
