Output of fs/list-dir (i.e. UnixPath) cannot be passed as-is to shell

[fosskers]

shell (etc.) from babashka.process can accept a :dir argument, but it seems that this value cannot accept a path found via fs/list-dir.

This would be useful in the case where you want to programmatically call shell in some directory, but you don't know ahead of time which one it is. For now, calling str on a path given from fs/list-dir gets around the issue, but it would be convenient if the original type could be passed directly.

Thank you!
