cmake: Added fing_pkg for WaylandClientPrivate (#21)

Use nixbuild/nix-quick-install-action which pairs well with
nix-community/cache-nix-action.

Should help with build times by reducing the number of packages needing
to be re-downloaded on each run.

Parameters are taken from https://github.com/nix-community/cache-nix-action
and may be tweaked later.
