Regression introduced by 5184aaa1ea.
The fix was intended to remove the "x == true/false" assertions, but by
accident a "x == false" was made "x == true" instead of "(!x)".

Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
