[cairo] [PATCH 2/2] test: Release owned pattern

[Andrea Canciani]

The pattern created by cairo_pattern_create_rgb() is owned by the
caller, hence it needs to be released.

Fixes:

malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
_cairo_pattern_create_solid (cairo-pattern.c:605)
_cairo_pattern_create_in_error (cairo-pattern.c:628)
cairo_pop_group (cairo.c:552)
test_cairo_push_group (api-special-cases.c:157)
preamble (api-special-cases.c:1766)
main (cairo-test-runner.c:228)
