wayland/glcontext: Don't call wl_surface.offset on old objects

The availability of wl_surface.offset depends on the compositor, so we
can't call it unconditionally. Add a version check to so we only call
offset if we know we won't raise a protocol error.

Fixes: 0eb791eaaa ("Make mask nodes more versatile")
