Subject: [PATCH 1/2] wlroots: 0.11.0 -> 0.12.0

The libseat session backend [0] will be disabled for now since NixOS
depends on systemd anyway (so we can use logind).
But if someone wants/requires libseat [1] and would maintain it in
Nixpkgs we could enable it.

Subject: [PATCH 2/2] sway: Fix the build with wlroots 0.12.0

Sway 1.5 isn't affected by the breaking changes of wlroots 0.12.0 so we
can simply relax the version requirement.
