Frederik Rietdijk 31e32b6d9e Python interpreters: add pkgs attribute
A package set is constructed for a specific interpreter. Therefore, we add the
possibility to override the package set to the interpreter. This should make it
easier to override the interpreter and the package set at the same time.

Python is a remarkably powerful dynamic programming language that
is used in a wide variety of application domains. Some of its key
distinguishing features include: clear, readable syntax; strong
introspection capabilities; intuitive object orientation; natural
expression of procedural code; full modularity, supporting
hierarchical packages; exception-based error handling; and very
high level dynamic data types.
