configure: add a check for a missing Intel TSS API (Esys_TR_GetTpmHandle)
Without it handle abstraction can't be done properly, so it is fairly
essential to the operation of the TSS. The check is done as a library
functional check instead of a version in case this rather essential
API gets backported.
