I don't think that depending on diff and less is the right solution for
that problem, because then enabling testing will change the system that
is meant to be tested.

For example, suppose that the real system only has busybox and busybox
diff needs to work. That version of diff cannot be tested anymore with
IMAGE_FEATURES += "ptest-pkgs" because that will pull in gzip-ptest,
which then overrides the busybox diff.

Perhaps the tests can be fixed to work also with busybox, or the tests
can detect busybox and skip the part that depends on real diff and less?
