Subject: overrides: Refactor into different override types.

We now have arg overrides and derivation overrides. Both are implemented using
mapOverride, which allows to specify overrides in batches using dotted attrset
nesting.

In addition new packages are now clearly separated away and alphabetically
ordered, so that it's easy to add another new package to the list.
