First, the .pc file was so far fixed as a post-configure hook of the
matchbox-fakekey package, by directly tweaking the .pc file installed in
staging by matchbox-lib. That's uterly wrong and bad.
So, we move the fix to matchbox-lib.
Second, it was incorreclty tweaking the .pc file when xlib_libXft was
not enabled, because only then a path to staging was present.
Third, even when xlib_libXft was enabled, the tweaking was still wrong,
because unnecessary.
Fix all that.
