osmocom-latest-packages.sh: Catch latest tags outside master branch

Some projects, like osmo-trx, may have tags created in a non-master
branch. Let's catch those too.

Tested with several osmocom repositories. The ones showing different
behaviour are osmo-trx (expected) and other repositories which have
wrong or no tags and are anyway not used since there's no OBS build for
them.
