Fix $$OUT_PWD not beeing set for finding the target/destdir

Qt Creator wouldn't find the correct target if shadow building a project
that uses $$OUT_PWD, like for example itemviews-ng.
We didn't set the necessary variable on the ProFileReader *, simplified
the code to always use a ProFileReader created for the exact
profilenode.
