ScottW514 ed1322518b forgetest: the lint takes python -m unittest given a test's file or module
forgectrl's CI runs its dev-server mock test as
`python3 -B -m unittest -v tests/test_devserver_mock.py`, and the
workflow judge counted python -m unittest only as `unittest discover`:
a HOST_TESTED row for that test was refused as not run.

_unittest_names: an argument to python -m unittest (not discover) runs
the test when it is the test's file (resolved against the step's
working-directory) or a dotted name whose module is that file
(tests.test_x, tests.test_x.Case.test_one); a -k pattern's value and an
argument with a shell variable are not names.

Proof: host tests: the CI's own command line, a module, a module with
a class and a method; not a module beside it, nor a -k pattern naming
it. The manifest tests (34) pass, and the forgetest host suite passes
under Linux. Against forgectrl's pinned workflow a row for
tests/test_devserver_mock.py is accepted; every earlier verdict on the
real workflows is unchanged.

Acceptance: none. forgetest is dev-only and in no fingerprint; the
lint runs in CI, not in a campaign.
