Only check the well-known password if we know it is not owned.

This fix ensures that we only try the well-known owner password if the TPM is not fully owned by checking for the presence of the .tpm_owned file.  Otherwise, each boot would cause a failed password attempt, which, on some TPMs, can eventually get the TPM into defend lock state.
