restore-backup: Run zulip-puppet-apply before pg_restore.

This should ensure that we apply any special configuration for the
database system (e.g. installing `pgroonga`) before we try to restore
the database contents from the archive.

For pgroonga in particular, this is important so that we can preserve
the configuration of the extension in the `pg_restore` process.

Fixes #12345.
