Adds support for non pkg-config tpm2-tss installs.

- Adds support for specifying path to the tpm2-tss libraries and
  header files using the environment variable ```TPM2_TSS_PATH```.
  The specified path is expected to have the following layout:
  | -> <Specified path>
  |    | -> include
  |       | -> tss2
  |           | -> tss2_esys.h
  |
  |    | -> lib
  |        | -> tss2_esys.lib (or .so)
