Avoid exit code overflow for tpmc.
In case of a TPM error, tpmc returns the TPM error code, which can
be greater than 255. In that case the error code is truncated.
Some error codes, such as TPM_E_RETRY, end with a zero byte,
resulting in a successful exit code. This is despicable.
BUG=chromium:234357
TEST=tested with exit codes < 255. Too hard to generate the others.
BRANCH=none
