Subject: posix-shell: utils: Add `lar()`

The list archive (`lar`) util creates a temporary directory, unpacks the
given tar archive into it, switches to that folder, starts the terminal
file manager `lf` and on quit jumps back and deletes the temporary
directory.

This is useful to quickly inspect the contents of a tar archive.
