Implement a class destructor to close the open TPM file descriptor and avoid the following error message:

I'd change it to "selftest: tpm2: Add Client.__del__() to close /dev/tpm* handle"

I don't recall seeing this. Does this happen on every test case?
Should better describe what is going on, e.g.
" The following output can bee seen when the test is executed:
test_flush_context (tpm2_tests.SpaceTest) ... \ /usr/lib64/python3.6/unittest/case.py:605: ResourceWarning: \ unclosed file <_io.FileIO name='/dev/tpmrm0' mode='rb+' closefd=True>
An instance of Client does not implicitly close /dev/tpm* handle, once it gets destroyed. Close the file handle in the class destructor Client.__del__(). "

No, only on that one test case.
