  lazy-expunge: Use mailbox_move() instead of mailbox_copy()

This allows some optimizations to be performed that are only possible when
moving messages.

It's slightly strange now that mail_expunge() is triggered twice for the
same source mail, but lazy_expunge plugin is called very early so most
plugins won't see it called twice. Currently only acl plugin sees it, and
it doesn't care.
