Fixed incorrect include/Qt/qconfig.h in binary packages.

When building from a source package, src/corelib/global/qconfig.h exists.
syncqt contained logic to force the creation of include/Qt/qconfig.h for
the case where it _doesn't_ exist.

This meant that running syncqt from a Qt source package resulted in
include/Qt/qconfig.h including qconfig.h twice.
