antergos-alerts doesn't work in KDE Wayland

[urbenlegend]

There are several issues with antergos-alerts when running on KDE Wayland.

1. Antergos alert doesn't show up
2. antergos-alerts pacman hook seems to slow down the Checking core system packages post installation step. I believe it's somehow waiting for the alert to pop up, but it doesn't work under Wayland so it blocks the installation until it times out.
3. There's no way to uninstall antergos-alerts without also uninstalling antergos-mirrorlist. I don't think the mirrorlist should depend on antergos-alerts. It should be perfectly fine keeping the mirrorlist without having the alerts.

Did some more digging. antergos-alerts will be called via this command: /bin/bash -c 'RECOMMEND_REBOOT=1 /usr/bin/antergos-alerts'. In KDE Wayland sessions, this command hangs for a while after you type in your password and then does nothing. In Xorg, this command correctly pops up the reboot alert after you type in your password.

I sometimes also see the message:

nologin: invalid option -- 'c'
Try 'nologin --help' for more information.

pop up every now and then when doing an update with pamac.
