rm contrib/perftest

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.

-## perftest : tool for benchmarking and profiling libpod library
-perftest uses libpod as golang library and perform stress test and profile for CPU usage.
-
-Build:
-
-```
-# cd $GOPATH/src/github.com/containers/libpod/contrib/perftest
-# go build
-# go install
-```
-
-Usage:
-
-```
-# perftest -h
-Usage of perftest:
-
--count int
-        count of loop counter for test (default 50)
--image string
-        image-name to be used for test (default "docker.io/library/alpine:latest")
-
-```
-
-e.g.
-
-```
-# perftest
-runc version spec: 1.0.1-dev
