and read from incorrect offset 14 instead of 22.

Add a simple TPM emulator for sandbox. It only supports a small subset of
TPM operations. However, these are enough to perform common tasks.
Note this is an initial commit to get this working, but it could use
cleaning up (for example constants instead of open-coded values).
