[debugging] Fix gdb script koid refs & panic CPU display

Browse Source 
Two minor debugging helpers:

- the GDB script was still referencing m_koid on objects, switched to
  the replacement m_obj_id instead.
- finally gave in and made panic print 1-based CPU ids like GDB uses
  instead of 0-based like the hardware and LITERALLY EVERYTHING ELSE
