This got missed for the current version, so I'm resubmitting for the

lcptools-v2/pconf_legacy.c: Add missing BE size_of_pcrs to hash buffer

First fix attempt was almost correct. System still doesn't boot with 
PCONF element. I forgot 1 important line though. Once added, the system 
now boots with the PCONF element. Tested with both 1 PCR and 2 PCRs.
