Test all not_eq for family names.

Any early out checks must give the same answer as FcConfigCompareValue.
An accelerator was added for family names which treated all ops as if
they were FcOpEqual, giving the wrong answer for other non-equivalent ops
(for example FcOpContains or FcOpNotEqual).

This adds a test which passes before the accelerator was introduced,
fails after, and will pass again after !142 lands. This tests the all
not_eq case.
