[PHP] Fix out typemap for member function pointers

The existing typemap was just broken - it correctly created the resource
and then did nothing with it, and instead tried to register the member
pointer as a normal pointer, which is never going to work as it's larger
than a normal pointer.

Add cpp_basic_runme.php as a regression test for this.
