[OpenBSD] Cannot find -name or -sname

[siegfried]

Steps to reproduce

Release any project and run its command with Distillery 2.0.12 on OpenBSD 6.4. It exits with a vm.args needs to have either -name or -sname parameter.

Paste the output of the release command you ran with the --verbose flag below in the summary tags (this helps keep the issue easy to navigate):

Description of issue

• What are the expected results? Start a console.
• What version of Distillery? 2.0.12
• What OS, Erlang/Elixir versions are you seeing this issue on? This issue occurs on Distillery 2.0.12, OpenBSD 6.4. Releases released by Distillery 1.5.5 were fine.

• If possible, also provide your rel/config.exs, as it is often It is the default one.

• Is there documentation that says one thing, but Distillery does another? If so, please link the doc here so it can be updated if I don't have a clue yet.
• If this is a runtime configuration issue, please also provide your config file (with any sensitive information stripped of course). This is almost I believe it is because the script cannot find the correct vm.args path, which exists at _build/prod/rel/my_project/var/vm.args

I've found the root cause and create a PR for it. Please have a look. My previous PR was to fix a tar command. We really need to be careful of the commands in macOS, I guess.
