[PATCH] selftests: tpm2: conform test to TAP output

[Muhammad Usama Anjum <usama.anjum@xxxxxxxxxxxxx>]

The python unittest is being used for executing tests. TAP output
cannot be added in the unittest framework. The python unittest is being
run from a script. Add the output TAP logs to the script. Add "#"
prefix to the python unittest output which will mark all output as
informational TAP messages. Check exit status of the python unittest to
decide if test passed or failed. Not sure why but python unittest
outputs logs in stderr. So redirect the logs to stdout and then add
prefix.

Specify the bash explicitly instead of sh to run these tests as all of
the kselftests are shifting towards using bash explicitly. Some
interpreters have different syntax and cause issues.
