Make sure to convert absolute paths generated using the
$<TARGET_LINKER_FILE> generator expressions into relative paths.
Because prl files are generated for both modules and plugins, we need
to pass both a list of qt module locations and qt plugin locations
to QtFinishPrl.cmake, and then try to make the absolute path relative
to each passed directory.
A warning assertion is shown if we no relative path could be made,
which will cause an absolute path to be embedded. This should not
happen though.
