scripts/gdb: mm: cast untyped symbols in x86_page_ops

The symbols phys_base, _text, and _end, used in x86_page_ops are either defined in assembly or implicitly by the linker. Thus, they lack type information and cause a conversion error after gdb.parse_and_eval. Explicitly cast these expressions to unsigned long.
