Unable to build a devcontainer features with podman

[lmilbaum]

Since version 0.54.2, building a devcontainer with podman on a macOS M3 is broken. It works with version 0.54.1. It seems related to the issue #548

I think the z flag only makes sense for Linux hosts. I will add a check for that.

Thanks for driving this. I don't know how your CI works but GitHub Actions provides a mac runner. It might be useful for cases like this one.
