Subject: [PATCH] nixos services.xserver.displayManager.session: drop type

For now at least.  I expect someone will find a working type later.
It's incorrect and was causing bad issues.  Example test case:
nix-instantiate nixos/release.nix -A tests.xfce.x86_64-linux --dry-run

This is a partial revert of commit b2d803c from PR #162271.
