[test] support using a previous build as a reference
Allow using a previous test output directory as a source of
reference images. To make use of this, set the environment
variable 'CAIRO_REF_DIR' to point at an old test directory,
relative to the current test directory.
This is useful for testing backends when reference images haven't
been created yet, or which the current reference image structure
can't accomodate, like multiple font backends.
