Perftest was intended to be used for testing CPU intensive tasks of
Podman. However, it does not compile for a long while and is not
integrated in the CI which clearly indicates that it has not been
used for a considerable amount of time.
Remove contrib/perftest entirely. If the desire arises to revive it,
all code is still reachable in the git history.
