compositor: move tests quirks initialization to weston_compositor_create()

Until now we had the test quirks initialization in wet_main(),
just after calling weston_compositor_create(). But there are
some cases that require the quirks during struct weston_compositor
creation time.

Move test quirks initialization to weston_compositor_create()
in order to cover more use cases for the test quirks mechanism.
