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. Change-Id: I7f636739a719908763bca1d3e7376341dd62e816
