login: fix session_kill(..., KILL_LEADER,...) (#35105)

Browse Source 
`loginctl kill-session --kill-whom=leader <N>` (or the D-Bus equivalent)
doesn't work because logind ends up calling `KillUnit(..., "main", ...)`
on a scope unit and these don't have a `MainPID` property. Here, I just
make it send a signal to the `Leader` directly.
