piem-edit-patch-am: Relay piem-am-ready-mbox's format

piem-edit stores the format returned by piem-am-ready-mbox in a
buffer-local variable, piem-edit-patch--format.  However,
piem-edit-patch-am doesn't use this value when it calls piem-am,
instead passing a hard-coded "mbox".

Pass piem-edit-patch--format so that git-am is called with the
appropriate format.
