improve nix dev shell; override the nixpkgs waybar

for example, the update from 0.9.16 to 0.9.17 broke this flake, after
this change the derivation will be the same as the nixpkgs one. This is
the better option since the flake is unmaintained in this repo (although
it may still break inbetween releases)
