Fix developer warnings that a plugin does not belong to a Qt module

When building qtsvg or qtimageformats there are a bunch of
configuration warnings like:

The plug-in 'qtiff' does not belong to any Qt module.

This happens because qt_get_module_for_plugin() checks for modules
only in the QT_KNOWN_MODULES variable. find_package()'d modules
will not appear there though, but only in
QT_ALL_MODULES_FOUND_VIA_FIND_PACKAGE.

Change the function to check for Qt modules in both variables.
This fixes all the warnings regarding plugins not belonging to a
module.
