[lldb/Utility] Fix a bug in stringify_append for printing addresses.

The recent change in the API macros revealed that we were not printing
the pointer address for a bunch of methods, but rather the address of
the pointer. It's something I had already noticed while looking at some
reproducer traces, but hadn't made it to the top of my list yet. This
fixes the issue by providing a more specific overload.
