[ModuleMap] Add more module entries to cover some non modular headers

These modules are necessary on Darwin to allow modules with
'no_undeclared_includes' (introduced in clang r284797) to work properly
while using libc++ headers.

Patch extracted from a suggested module.modulemap from Richard Smith!
