system tests: new rm, build tests

- rm: confirm 'rm' and 'rm -f' on running container

 - build: shotgun test of workdir, cmd, env, labels

The new build test cd's to a temporary directory, which broke
test invocations using a relative path (./bin/podman). Added
code to detect relative paths and convert them to absolute.
