[games-fps/unvanquished] fix dependencies
Fix #64
Are these runtime dependencies?
No. They are not: https://github.com/Unvanquished/Unvanquished/blob/master/README.md Fixing this.
You're missing PYTHON_USEDEP. Pyyaml and jinja don't have binaries, so the modules are imported.
I haven't seen any other uses of python_gen_any_dep from python-any-r1, so I'm not sure, but it seems working.
