(opm) Introduce deprecatetruncate for opm registry (#804)

This PR exposes the `deprecatetruncate` functionality, previously
only included under `opm index`, under `opm registry`. In line with
all other commands that operate on a sqlite db, this sub-command is
deprecated too. In line with `opm index deprecatetruncate`, the
`deprecatetruncate` sub-command for `opm registry` is hidden too.
