feat(nix/writeExecline): add writeExecline r/1100

This is a writer, similar to `pkgs.writeBashScript` or
`pkgs.writers.writePython3`.

The difference is that we can correctly write all execline scripts by
using nix lists of lists, so the user doesn’t have to care about
escaping arguments (like they have to in bash scripts with
`lib.escapeShellArg` for example).
