secure-boot: Log an error if TPM measurement fails

Log an error if the TPM measurement fails due to the absence or
invalid value of the file '/sys/class/tpm/tpm0/pcr-sha256/0'.

Tested:
Verified that an error is logged when '/sys/class/tpm/tpm0/pcr-sha256/0'
is absent, empty, or has a value of 0, indicating that the TPM
measurement has failed.
```
