The various /bin/tpm2_* binaries use dbus to communicate
with tpm2-abrmd and also can directly access /dev/tpmrm0. This
seems like a way to help limit access to the TPM by running the
tpm_* binaries in their own domain.
I setup this domain because I have a process that needs to use
tpm2_hmac to encode something, but didn't want that domain to
have direct access to the TPM. I did some basic testing to verify
that the other tpm2_* binaries have basically the same access needs.
But it wasn't through testing of all the tpm2_* binaries.
