Add bootStdenv condition around the overrider.

This condition used to be implicit in the sense that the stdenvOverrides
uses pkgs_6, instead of pkgs_7 as its super set, and also that each stage of
the compiler is build again the bootstrap packages of the previous stage,
thus overriden by the stdenv.override function.
