VTL: Allow running simple unittest.TestCases.

It came to my attention that Ole added a simple test in:
https://gerrit.fd.io/r/#/c/16381/ and the framework forced him
to launch an instance of VPP to test the formatting of a mac address.

This change allows the test framework to run standard unittest.TestCases
without the need to spawn a VPP instance.
