FreeBSD: Disable broken tests

Disabling a few tests. The distributed tests are failing for the same
reason they fail on Linux, the rpaths and library search paths are
mucked up. Fixing that shouldn't be too hard, but should be enabled on
both platforms at once.

CollectiveTransformers doesn't work because it imports Darwin directly.
There is a note that is several years old saying that we should port the
test to the other platforms, but that is beyond the scope of this PR at
the moment.
