taffybar: Remove strictDeps and restore overrideAttrs

[srhb]

Motivation for this change

Get rid of now-unnecessary overrides for strictDeps and pkgconfig gtk3, restoring overrideAttrs.

taffybar still does not compile because the current Hackage release does not support gi-gdkpixbuf > 0.16 but should be fine with the next release, eg. this overlay builds, or one that downgrades gi-gdkpixbuf:

  haskellPackages = with self.haskell.lib; super.haskellPackages.extend (hself: hsuper: {
    # Supports gi-gdkpixbuf 2.0.18
    taffybar = if !(hsuper.taffybar.version == "3.1.1")
    then "taffybar overlay out of date"
    else (
      hsuper.taffybar.overrideAttrs (oa : {
        src = self.fetchFromGitHub {
          owner = "taffybar";
          repo = "taffybar";
          rev = "e382599358bb06383ba4b08d469fc093c11f5915";
          sha256 = "0qncwpfz0v2b6nbdf7qgzl93kb30yxznkfk49awrz8ms3pq6vq6g";
        };
      })
    );
  });

cc @puffnfresh so you can confirm that it's safe to get rid of strictDeps now. :)
