Supporting Generics on Classes Annotated with @SuperBuilder

[Nathaniel Troutman]

I've run into an issue where using @SuperBuilder on a class with Generics fails if you try to customize the constructor that accepts the builder class.

For example this fails with the error `error: constructor Parent(ParentBuilder<T,?,?>) is already defined in class Parent`:

```
@SuperBuilder
public class Parent<T> {
  int field;

  protected Parent(ParentBuilder<T, ?, ?> b) {
    if (b.field == 0)
      throw new IllegalArgumentException("field must be != 0");
      this.field = b.field;
    }
}
```

I'm happy to contribute the fix as I already know where the bug is and done a quick POC. Is this something that would be beneficial?

Hi Nathaniel!

Yes, I consider this a bug. If the customization works for non-generic
classes, it should work for classes with type parameters, too.
I'll review the PR once you are finished.

Best regards
Jan
