Export all Python builtins to the templates, instead of one-by-one.
Export all Python builtins to the templates, instead of one-by-one.

This commit drops the manual export of certain builtins to the template context
and just exports all Python builtins. We don't lose any security here, because
the templates have full access to the runner through other mechanisms anyway.
This commit also stops constructing `namedtuple`s to fake modules and just
exports the modules themselves. This should have no noticeable effect on
functionality unless your template is shadowing a builtin.
