Fix nmigen "domain" error when trying to run unit tests

When I try to run any unit test with nmigen c42c3a0, I get the
following error:

Traceback (most recent call last):
  File "/usr/lib/python3.8/runpy.py", line 193, in _run_module_as_main

    fragment.domains += ClockDomain("sync")
AttributeError: 'FPMULMuxInOut' object has no attribute 'domains'

This seems to fix this error by giving the functions in the testbench
a default clock domain, rather than leaving it up to nmigen to figure
out.
