Remove dj-beets project

No longer in use. Drops the beets containers (cli/web), build +
autoimport services and timer, the beet CLI wrapper, /opt/dj-beets
tmpfiles entry, firewall port 8337, the Makefile copy step, and the
src/dj-beets tree (which contained a Beatport token) so the repo can
be made public safely.
