Skip tsl unit test when we hit an error due to OpenSSL and junos-eznc…

… packaging conflict

he pip junos-eznc package, when installed with PyOpenSSL version 0.14 causes
this test failure. If you either remove junos-eznc, or upgrade PyOpenSSL
(current is 0.17) the test is happy. So, we need to handle this case in the test.
