[mutter] Pass CoglContext to cogl_texture_pixmap_x11_new()

[Robert Bragg <rbragg src gnome org>]

commit d249cfd040c6df402730b12b990666cfee52a2d2

    Pass CoglContext to cogl_texture_pixmap_x11_new()
    
    The experimental Cogl api cogl_texture_pixmap_new() was recently changed
    so it now expects an explicit CoglContext argument and it can also
    return exceptions now via a GError. This patch updates mutters use of
    the api accordingly.
