Pekka Paalanen 091b1554da shared/cairo-util: fix leak from load_cairo_surface() 
Fixes ASan reported leaks:

Direct leak of 256 byte(s) in 1 object(s) allocated from:

from the command

	ASAN_OPTIONS=fast_unwind_on_malloc=0,malloc_context_size=50 \
	LSAN_OPTIONS=suppressions=/home/pq/git/weston/.gitlab-ci/leak-sanitizer.supp \
	./tests/test-viewporter test_viewporter_bad_source_rect

by recording the pixman image as user data so it can be freed when the
surface is destroyed.
