python3.pkgs.qtile: remove unneeded dependencies

In Qtile's v0.34.0 update in 1da6cbd149, it started using wlroots
directly instead of using pywlroots. See:

https://github.com/flacjacket/pywlroots/issues/201#issuecomment-2641298020

And in particular:

https://github.com/qtile/qtile/blob/v0.34.0/CHANGELOG#L8-L10

`pywlroots` also is using explicitly wlroots_0_17, per:

https://github.com/NixOS/nixpkgs/blob/1f40d75362b84e714727cd322f809d265ec82fd2/pkgs/top-level/python-packages.nix#L15852

And these wlroots versions contradict each other.
