instead of checking in build time as it's runtime dependency.
Also log when tsspcrread not found to make debugging easier.
We search for tsspcrread unless there is tss2-esys with Esys_PCR_Read(),
thus pcr_none.c was dropped as unneeded.
file_exist(), tst_get_path() and MIN() taken from LTP project.

This patch makes it possible to use the Intel TSS2 for getting
PCR values from the SHA1/SHA256 banks on a TPM2.
It is somewhat naive as it doesn't use the multi-PCR selection
that TSS2 is capable of, that is for a future patch.
