Subject: [PATCH] sway: Fix the build

While the last wlc upgrade (05d79c03ec36f8d49d1e2bf2b750c3943c348377)
makes it possible to build sway 0.14.0 it also breaks the current build
of sway 0.13.0.

Unfortunately sway 0.14.0 segfaults on launch and I couldn't fix it yet
(there are multiple upstream issues as well). I'll overwrite the wlc
version for sway in order to have a usable version in nixpkgs for the
meantime.
