Clean up any/all stale partition tables.

When formatting media as a public volume, we write an MBR, but we
might leave a stale GPT floating around.  Some devices are configured
to aggressively prefer GPT when detected, even if the checksums
between primary/secondary don't match.

To work around this, nuke both MBR and GPT tables from the media
before we lay down our new MBR.
