swh: ‘lookup-origin-revision’ handles branches pointing to directories.
Fixes <https://issues.guix.gnu.org/69070>.

* guix/swh.scm (branch-target): Add clause for 'directory and 'alias.
(lookup-origin-revision): Iterate over all the visits of ORIGIN instead
of just the first one.  Handle the case where ‘branch-target’ returns
something other than a release or revision.
* tests/swh.scm ("lookup-origin-revision"): New test.
