Checking for TPM version. TPM2 < 1.38 will not be supported.

[schubi2]

Problem

systemd-pcrlock is using PolicyAuthorizeNV to store the policy inside
the TPM2's non volatile RAM. This feature is supported after TPM2 1.38
revision, and without it systemd-pcrlock will fail. These PR checks
for version > 1.38 (bsc#1250403)
tpm_fde is not affected because it is using it's own tool to recognize TPM.
