The `overridePythonAttrs` method is for overriding `buildPython*` builders. Packages that use `toPythonModule` directly are typically bindings build not using `buildPython*`. This commit allows also those packages to be overridden with `overridePythonAttrs`, insteading actually invoking `overrideAttrs`. The motivation for this is to offer a common user interface for users of the Python packages set. This way they only need to know about `overridePythonAttrs` when overriding the builder, and `override` when overriding the `callPackage` call. Related RFC NixOS/rfcs#67.

Problems:
- This is not composable: You can't
overridePythonAttrstwice overrideAttrsdoesn't support non-functions, so.overridePythonAttrs {}fails, leading to inconsistent behavior with theoverridePythonAttrsthatmakeOverridablePythonPackagedefines.

I see. Any suggestion how this can be resolved by adding the override option after the original function (stdenv.mkDerivation) has already been called? This here also seems a case where NixOS/rfcs#3 would be helpful.

Usually this is done by calling the original function again, but I think this get really messy with multiple ways to override things. Maybe look at the implementation of makeOverridable
