qt4-x11-free: bring back pkg-config fixups

* With b40b9c024be5e1ec81a31961158b3e6b529acfe0 some pkg-config fixups where removed from
  qt4.inc which breaks the pkg-config files for qt4-embedded. Without that the pkg-config
  files for qt4-x11-free are broken. So this patch puts the fixes into the qt4-x11-free.inc
  file to be used by qt4-x11-free and not qt4-embedded.

* Resending because nobody replied on
