Reorganize pc files for a single library

After this commit, pc files no longer include the gdk backend in
their name, and we no longer install a pc file for gdk. There is
now a single gtk+-3.0.pc file. It turns out a separate gtk+-x11-3.0.pc
file is not necessary, since gdkx.h doesn't have a separate include
directory that would have to be added to Cflags.
