cmd/link: do not align type name data
Now that reflect.name objects contain an offset to pkgPath instead of a
pointer, there is no need to align the symbol data.
Removes approx. 10KB from the cmd/go binary. The effect becomes more
important later as more type data is moved into name objects.
For #6853
