vim_configurable: enable overrides

Browse Source 
Sometimes it's needed to override parts of `vim_configurable`, for
instance when using ENSIME (http://ensime.github.io/), in this case you
need a Python interpreter and the modules `sexpdata` and
`websocket_client`.

However overriding `vim_configurable` is quite hard as we run
`vimUtils.makeCustomizable` over the default comming from
`configurable.nix`. Therefore it's necessary to copy the code from
`all-packages.nix` and alter the parts you need: https://nixos.org/nix-dev/2017-April/023364.html

In order to simplify overriding `vim_configurable` I added an
`override` and an `overrideAttrs` function to `vimutils.makeCustomizable`
to ensure that the customization capabilities won't be lost after
altering the derivation.

Now it's possible to write expressions like this without evaluation
failures:

```
with pkgs;

let
  vimPy3 = vim_configurable.override {
    python = python3;
  };
in vimPy3.customize { ... }
```
