feat(su): add run0 to the list of alternative privilege elevators

[sylv-io]

systemd 256 introduces the run0 based on systemd-run, as an alternative to sudo/doas without being a SUID binary.

TODO:

• [ ] Add config tests
• [ ] Add --background= flag to prevent red background color

Greetings, With ArchLinux now using systemd 256, it is time to support run0. I added it to the list after doas, but imho it should be prioritized since it is available by default with the systemd package.

Any thoughts?

I agree, I think run0 support should be better :+1:, I should make more of an effort to use it myself
