python: Better sort dictionary keys/values

In Python 2, dict.keys() and dict.values() both return a list, which can
be sorted in two ways:

* l.sort() modifies the list in-place;
* sorted(l) returns a new, sorted list;

In Python 3, dict.keys() and dict.values() do not return lists any more,
but iterators. Iterators do not have a .sort() method.

This commit moves the build scripts to using sorted() on dict keys and
values, which makes them compatible with both Python 2 and Python 3.
