Add build test for .containerignore tar file

Ensure a directory added to .containerignore on client is not included
in tar sent to remote podman API service

* Clean up podman invocations to not include duplicate --remote and
  --url flags
* Use pkill vs. pgrep when cleaning up podman API service in tests
* Add exit code when logging error when testing

Closes #13535
