There are some constraints on selftests for usability reasons, adding
too many dependencies and too exotic a set of dependencies works against
that - we already disable the BPF tests by default because it is not
reasonable for people who are not actively working on BPF to be able to
get the dependencies needed for the testsuite up and running and it was
causing disruption to people trying to actually use kselftest for actual
testing.  Of course there's a balancing act here with having the tests
picked and used by people but the kernel is such a big piece of software
it seems reasonable to expect that we're not going to end up with
everything in one place, and if it's not solving a practical problem for
the people actively working with the tests it really doesn't seem like a
good use of the limited time people have to work on quality stuff.
