muffin: move *.gir and *.typelib files

Other packages have *.gir files in usr/lib/gir-1.0 and the
*.typelib files in usr/lib/girepository-1.0. The usr/lib/gir-1.0
directory should then be in the muffin-devel subpackage AFAICT.

This is in a try to fix the cinnamon cross build yet it isn't sufficient.
