tests: use mocks to allow calling virEventRegisterImpl many times

We currently have to run each of the test_aio.py test cases in a
separate process, because libvirt.virEventRegisterImpl can only be
called once per process. This leads to quite unpleasant console
output when running tests.

By introducing a mock for libvirt.virEventRegisterImpl we can
regain the ability to run everything in a single process. The only
caveat is that it relies on tests to fully cleanup, but in practice
this is ok for our current tests.
