xwayland/glamor: Track if a xwl_pixmap uses explicit modifiers 

If we allocated with implicit modifiers, then we shouldn't use the
modifier returned by gbm_bo when checking whether the modifier is
supported or not, since it won't be if the compositor only advertises
implicit modifiers, nor should we use the modifier when creating the
Wayland buffer object, as it wasn't explicitly advertised.

Fixes: c6f2598a4 ("xwayland: don't fall back to wl_drm with explicit modifier")
