more BATS tests

- run: --name (includes 'podman container exists' tests)
- run: --pull (always, never, missing)
- build: new test for ADD URL (#4420)
- exec: new test for issue #4785 (pipe getting lost)
- diff: new test
- selinux (mostly copied from docker-autotest)

Plus a bug fix: the wait_for_output() helper would continue
checking, eventually timing out, even if the container had
already exited (probably because of an error). Fix: as
part of the loop, run 'podman inspect' and bail out if
container is not running. Include exit code and logs.
