This address two issues with Zef::Service::Shell::tar on OpenBSD.
The first is detecting tar in the first place.
Previously zef tried to detect tar on OpenBSD by looking for some magic words in the output of tar, since there's no --help or --version option.
Currently (as of OpenBSD 7.4) running bare tar doesn't produce any of those magic words, so detection fails -- this is true back until at least OpenBSD 6.8.
This patch changes the detection to run tar -cf -, which will exit silently with code 0 if tar is runnable.
The second issue is a missing -z in ls-files; GNU tar will list a gzipped tar without complaint using just -t -f; OpenBSD tar will not and requires the -z option. Adding this mirrors usage in extract.
