Subject: [PATCH] programs.i3status-rust: reload on config change (#4466)

Adds automatic reloading of i3status-rust on config change.
This is done via sending SIGUSR2, which is now supported since [v0.20.0](https://github.com/greshake/i3status-rust/blob/master/NEWS.md#new-blocks-and-features-21)

The previous method of attempting to restart i3 in its entirety didn't work at least on my system, and is now overkill anyways.
