qt5wayland: add fix from upstream to compile without QtQuick

Compiling qt5wayland fails if you do not have the QtQuick module:

Fix taken from upstream's git:
http://code.qt.io/cgit/qt/qtwayland.git/commit/?id=2c48ee65e8c3b894caec214641723d0777fc60b8

No longer depends on declarative after applying either.
