upload_and_update.py: Add --noprepare option

When the BMC is already in state for update, e.g. already rebooted with
loop deviced mounted for rofs, or in netboot without rofs mounted, it is
possible to directly do the update without "prepare".

This option is added for such case, so it saves a "prepare" progress
and thus saves a reboot time.
