That's an interesting idea, but the directory it (and /sys, /dev, etc,
eventually, I suppose) needs to be mounted on doesn't exist until we're
late into "make check" and rsync'ing the pristine test container to the
working test container.  And we delete and rebuild that container as
needed.  It would be a lot of messy logic to pre-mount that.

I talked with Carlos about this a bit and he suggested we could add a
support_need_special_mounts() that just exits UNSUPPORTED if mounts like
/proc are missing, for tests that rely on such.  I'd rather not wait for
that for this patch, though, as this patch at least enables more PASSing
tests in the CICD stuff.
