vboot: use out_flags to indicate recovery mode 

In order to make the proper decision on loading the
option rom or not the recovery mode setting needs to be
known.  Normally this is detected by asking the EC,
but if recovery is requested with crossystem then the EC
does not know about it.  Instead we need to check the
output flags from VbInit().
