Subject: [PATCH] mastodon: refactor passthru on source

Any attribute concatenation onto the result of mkDerivation will break
*some* overrideability.

This case is rather obscure. You'd have to do something like this to get
an eval failure:

```
(mastodon.override { srcOverride = mastodon.src.overrideAttrs { }; })
```

This is not what I'am actually doing: I am calling `overrideAttrs` on
every `callPackage` call for an experiment - and this break with it.
