Cantarell: drop the stale FontForge config.yaml override

The family now has a source repository with sources/config.yaml, referenced by
config_yaml in METADATA.pb; this local override still pointed at the old
FontForge .sfd sources (which are not present here), so google-fonts-sources
would build from nonexistent files. Removing it.
