[utilities/filelight] src: Only set the QtQuick style if it wasn't done by the QPT before

Only set the QtQuick style if it wasn't done by the QPT before

Rather than just always setting the style if the QT_QUICK_CONTROLS_STYLE
environment variable was not set, copy the logic from
KirigamiAppDefaults of kirigami-addons to check if the style has not
already been set by the QPT. This allows other styles than desktop style
to work if the QPT sets them.
