Testing for QT.widgets.name in qtmultimedia.pro causes the behavior of
that .pro file to depend on whether or not qtbase.pro has been
processed. Due to QTBUG-23376, and because these are sibling .pro
files, this is not safe - nothing guarantees that qtmultimedia.pro is
processed after qtbase.pro.
Work around the issue by pushing the QT.widgets.name test down one
level.
