Revert "xorg: mark fonts with proprietary licences as unfree"

This reverts commit c451603
and hopefully fixes #99236: evaluation on Hydra.

For lack of a better method, I used the live jobset to bisect.
On the reverted commit it failed (tried several times because sometimes
evaluation fail transiently, possibly due to exhausting some resources)
and on the parent it succeeded: https://hydra.nixos.org/eval/1617490

Right now I don't have energy to find what exactly is wrong in the
commit, and it doesn't seem important in comparison to nixos-unstable
channel being stuck on a commit over one week old.
