e wl halt/reboot/logout restart fix - dont restart

so when e was e.g. shutting down the system it'd sometimes - or all
the time, restart and not shut down. this fixes that. e was being sent
a HUP signal while doing this causing e to go "ooh HUP - i shall
restart" which si what daemons without a controlling tty do with
signals commonly. this isn't what we want from e though in this case,
so delay itby a bit and ignore if we're in the process of logging
out/halting etc.

this really only affects wayland mode.
