udev: String substitutions can be done in ENV, too

Precedence for example in https://github.com/systemd/systemd/blob/ac63c8df309e37960618610d8b57ac19ac657254/rules.d/99-systemd.rules.in#L75.

Add ENV to the list of keys where string substitutions can be used.

While I'm at it, also sort the list in that paragraph alphabetically.
