Michał Żygowski 6cec520515 util/cbmem/cbmem.c: Avoid overflwos when parsing TCG TPM logs ...

The utility assumed that TCG TPM log area is zeroed and then filled
with events but it does not have to be true. If there is garbage
after the last valid event entry, the utility will most likely
access data outside of the cbmem area containing the logs. Relevant
issue: https://github.com/linuxboot/heads/issues/1608

TEST=Dump TCG TPM1.2 event log on Dell OptiPlex 7010 and see
"Invalid TPM1.2 log entry overflowing cbmem area" error is printed.
