archivers/file-roller: Add missing dependencies and fix build when NAUTILUS off

Poudriere reports two linked libraries missing from file-roller
dependencies.

The one on libhandy causes it to fail to build when the NAUTILUS
option is disabled. The libhandy library happens to be already
installed by nautilus when that is present as a dependency, but the
port fails to find it when nautilus and its dependencies are not
already present in the system or poudriere jail at build time.
