Subject: [PATCH] gsk: Allow custom fonts in tests

The commit adds a custom fontconfig configuration in
testsuite/gsk/fonts/fonts.conf and sets the FONTCONFIG_FILE
environment variable for the gsk compare tests to point at it.

To use a custom font in tests, just drop it into the
testsuite/gsk/fonts/ directory.

The font configuration includes the system configuration,
so existing tests should not be affected.
