networkd-tests.py: remove some java-style boilerplate

A class was used to put some utility functions under a namespace. But then this
namespace was inherited into classes, so the namespace split was undone. Let's
just define those functions in the module namespace.

(The Utilities class with a few functions still remain, because of the
unittest-style self.assert* craziness.)
