reboot, poweroff: Prepare TPM2 for shutdown
TPM2 must be prepared for shutdown, or it may track an auth failure for
dictionary attack prevention (per the spec, to prevent an attack by
attempting to authenticate and then powering off the TPM before it can
update the nonvolatile counter).

Add tpmr shutdown to prepare for shutdown (no-op on TPM1).  Invoke it
from poweroff and reboot.
