* make font derivations fixed-output where applicable
* fix dead links
* `stdenv.lib` -> `lib` where `stdenv` is not involved
* remove `meta.platforms = [ unix ]` and `meta.platforms = [ linux ]` because the restriction has no sense for data packages
Regression introduced by 9820cb1bf2.
The commit only sets dontBuild but the build for the DOSEmu fonts had a
dummy configurePhase as well.
So rather than just reinserting a dummy configurePhase again, let's just
use buildCommand and put it out in one go, which is more suitable for
such a simple package.
