[tboot] Add patch to fix timeout bug introduced by tboot.hg changeset 176.

Either the TPM in the hp6930p doesn't operate to spec or the code
was never tested.  With the patch, the values read from the tpm are
equal to the default values used before tpm timeout code was added
in changesets 163 and 176.
