    js: Use JS_NewObjectWithGivenProto
    
    In mozjs38, JS_NewObject() doesn't take a prototype JSObject anymore;
    instead, JS_NewObjectWithGivenProto() is used for that purpose. The
    behaviour of JS_NewObject() is changed so that it looks for a default
    prototype, which is the same as passing JS::NullPtr() as the proto
    parameter in mozjs31.
