Bug 1231314 - Turn mozilla-config.h and js-confdefs.h into CONFIGURE_DEFINE_FILES. r=gps

Both these files, are, after all, define files, like other CONFIGURE_DEFINE_FILES.
They only happen to have a special requirement for an expansion for all defines,
which doesn't need to happen through traditional preprocessing.

This change adds consistency in how configure-related headers are being handled.
