Support 'tpmc setbgloballock' for tpm2 case

Browse Source 
Some scripts call 'tpmc setbgloballock' or 'tpmc block'. For tpm2
it should be equivalent to pplock, i.e. perform rollback protection
actions: writelock for NVRAM firmware index and disable platform
hierarchy.

BRANCH=none
BUG=chrome-os-partner:55210
TEST=run 'tpmc block' on kevin, check that it attempts pplock
