sandbox: tpm: Enhance to support the latest Chromium OS
This driver was originally written against Chromium OS circa 2012. A few
new features have been added. Enhance the TPM driver to match. This mostly
includes a few new messages and properly modelling whether a particular
'space' is present or not.
