osstest: save/retrieve the last successfully tested FreeBSD build

And use it in order to install the hosts for the next FreeBSD flight.

Note that the anoints are done after the push, but there's a recovery
mechanism in case osstest manages to do a successful push, but the
artifacts are not anointed for some reason. Osstest will continue to
create flights until the revision of the anointed artifacts matches
the one pushed to the repository (even if that means running flights
with OLD_REVISION == NEW_REVISION).

Changes since v7:
 - Add space between $freebsd_branch and * in list-prepared.

Changes since v6:
 - Use just the branch name for anoint (instead of freebsd-$branch).
 - Force the creation of flights if the revision of the current
   anoints don't match OLD_VERSION.
 - Iterate over the list of current anoints instead of open-coding the
   arches.
 - Split the retrieve/anoint code blocks into it's own sections.

Changes since v5:
 - New in this version.
