pkgs: add builtins prefixes for prelude functions to improve clarity

# If we are passed a derivation (based on stdenv*), we can use overrideAttrs to

# update the arguments to mkDerivation. This gives us the proper awareness of

# what arguments were effectively passed *to* mkDerivation as opposed to

# derivation (by mkDerivation). For example, stdenv.mkDerivation

# builtins.derivation (by mkDerivation). For example, stdenv.mkDerivation

# accepts an `env` attribute set which is postprocessed before being passed to

# derivation. This can lead to evaluation failures, if we assume

# builtins.derivation. This can lead to evaluation failures, if we assume

# that drvAttrs is equivalent to the arguments passed to mkDerivation.

# See https://github.com/NixOS/nixpkgs/issues/269539.

if lib.isDerivation attrs && attrs ? overrideAttrs then

      else
