Replace the handrolled implementation in experiments/agx_1tri.py and tools/reset_panic_counter.py. In addition reset the panic counter in reboot.py and run_guest.py. If can reboot or start guests the boot process works fine and macOS recovery needs to leave us alone. Signed-off-by: Janne Grunau <j@jannau.net>
