[cairo] [PATCH] mask compositor: Set a check_composite method

Commit 503b6b9e2ea6 added a check_composite method to the mask compositor, but
only added it to one of the existing implementations. This commit fixes that.
In cairo-image-compositor.c, there is already a check_composite method which
just returns success for the traps compositor. This commit makes the mask
compositor use that one.
I don't want to say much about cairo-image-mask-compositor.c except that I
wondered why this file and the file above both define a non-static function
called _cairo_image_mask_compositor_get(). In my opinion, that file should just
be deleted, since it confuses e.g. ctags, but I'll let someone else clean this
up.
Fixes 493 crashes in the test suite for the test-mask target.
