test: Add rudimentary support to run selected tests only

To keep this simple, only support tests that have corresponding setup
and teardown functions implied by their path. For example:

  ./run passt/ndp

will trigger the 'passt' setup and teardown functions.

This is not really elegant, but it looks robust, and while David is
considering proper alternatives, it should be quite useful.
