meta: qt4: fix postprocessing of pkg-config files

When building qt4-embedded the generated and cleaned pkg-config files for qt are wrong.
The Cflags variable contains something like ${includedir}/qtopia/QtCore where
${includedir} is already /usr/include/qtopia/QtCore.

This patch reverts the fix up of the Cflags variable implemented in do_install.
