Bug 1257448 - Don't emit an error on unknown implied options when their resolved value is None. r=nalexander imply_option has no effect when the resolved value is None, so the same logic can be applied when checking for unknown implied options. This allows to imply options that may not always exist (because they are in a configure file that is optionally included). Ideally, it would be better not to do this, but until we have something better than optionally included configure files for --disable-compile-environment, this is a necessary evil.
