scripts/qemugdb: mtree: Fix OverflowError in mtree with 128-bit addresses

The 'qemu mtree' command fails with "OverflowError: int too big to
convert" when memory regions have 128-bit addresses.

Fix by changing conversion base from 16 to 0 (automatic detection based
on string prefix).  This works more reliably in GDB's embedded
Python.
