Address spec fie issues discovered in mutter-wayland review

- Update the description and URL from mutter.doap
- Tighten -devel subpackage deps with _isa
- Use the %make_install macro to avoid mixed usage of $RPM_BUILD_ROOT
  and %{buildroot}
- Drop 'Requires: pkgconfig' as rpmbuild generates this automatically
