go/analysis/passes/printf: update logic now that type parameters are
interfaces

Now that the underlying of type parameters is their constraint
interface, a couple places in the printf analyzer need to be updated:
 - We need to explicitly exclude type parameters when looking at
   interfaces in isFormatter.
 - We need to consider at the element type, not its underlying, when
   looking at pointers to type parameters
