[PATCH v2 08/22] tasst: Introduce library of common test helpers

[David Gibson <david@gibson.dropbear.id.au>]

Create a Python package "tasst" with common helper code for use in passt
and pasta.  Initially it just has a placeholder selftest.

Extend the meta tests to include selftests within the tasst library.  This
lets us test the functionality of the library itself without involving
actual passt or pasta.
