Replace one partial backlink hack with another

The WorkerGlobalScope hack no longer has any effect, so just use the
same hack for NavigatorID.

The only change in the output from this is that "also has obsolete
members" becomes "also has additional members in a partial interface".

Fixes whatwg/html#882
