Add a PCR extend call for measuring the dev mode boot flag.
BUG=2083
TEST=manual
Compiled with DISABLE_ROLLBACK unset. I need help testing this change - in particular, if the PCR 0 value is actually different in dev mode off vs. dev mode on. This can be done by invoking 'tpm_pcrread -p 0' at the shell. tpm_pcrread is part of the tpm_tools package.
