Title: fossil: fix head url causing recursive error in dependency tracking

When looking to add a `fossil://`-prefaced url for a new HEAD build for `libspatialite` (the first fossil:// repo usage?), I ran into `ERROR: Stack level too deep`. I assume this is because head url in `fossil` causes it to generate a dependency back to itself. Removing head section fixed issue.
