nixos/plasma5: fix mismatch between nix and module system

Browse Source 
In https://github.com/NixOS/nixpkgs/pull/254071, a mismatch between usage of
the Nix language and the NixOS module system was introduced. By merging the
kwin_wayland wrapper attrset into the mkIf representation, the former was
effectively ignored.
As a result, the capability wrapper for kwin_wayland stopped being installed,
leading to realtime scheduling being disabled. The issue was not detected
because the behavioral change is very subtle.

By consistently using language-level constructs, this mismatch is resolved.
The capability wrapper is thus installed again and realtime scheduling is
restored.
