fetchurl: Don't force-override curl's gssSupport to on unnecessarily #66506

Motivation for this change

Bug #66499

The original intent in commit a1fec86 treewide: assemble all `fetchurlBoot` uses in overrides to `fetchurl` itself was to turn gssSupport off on Darwin, but the code actually also forced
it on on Linux.

This resulted in previous (e.g. overlays) .override { gssSupport = false; } being ignored (#66499).

This commit fixes it by just respecting the old value when it doesn't need to be forced to off.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nix-review --run "nix-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

The original intent in commit

    a1fec86 treewide: assemble all `fetchurlBoot` uses in overrides to `fetchurl` itself

was to turn `gssSupport` *off* on Darwin, but the code actually also forced
it *on* on Linux.
This resulted in previous (e.g. overlays) `.override { gssSupport = false; }`
being ignored (NixOS#66499).

This commit fixes it by just respecting the old value when it doesn't need
to be forced to off.

Just for clarification, the previous version of the code was equivalent to this:

       gssSupport =
        if stdenv.isDarwin || stdenv.hostPlatform.isWindows
          then false
          else true

and I've made it this:

       gssSupport =
        if stdenv.isDarwin || stdenv.hostPlatform.isWindows
          then false
          else old.gssSupport or true; # `? true` is the default

we no longer need that workaround.
