translate: backup zanata db directly to borg

As noted inline, a recent mysql client update has broken the
"--all-databases" flag, at least for the client version and very old
server version we use.

Emperically, dumping individual databases still works with this
client.  Switch this to stream the db directly into borg.

Ignore the old backups and remove the bup backup while we are here,
since this is all borg now.
