runtime/map: update comment for gc/reflect

update comment cause gc/reflect.go has been moved to reflectdata/reflect.go

In the commit (attach below), gc/reflect.go is moved to reflectdata/reflect.go
So the  comment referring gc/reflect.go should be updated to reflectdata/reflect.go

There maybe other places that refers gc/reflect.go that should be updated.
I would work around it soon.
