build: Implement minimal GNOME Build API

One more step on the road to entirely eliminating the concept of
packages.  I adapted the installation rules from the Fedora
spec file.

They should clearly be less lame, but to do so we'd need more formal
rules about which files should be installed.  Maybe just limit it to
things ending in ".bin" or ".fw"?
