arm: Remove BreakPCEvent on guest kernel panic
The LinuxArmSystem class normally provides support for panicing gem5 if the simulated kernel panics. When this is turned off (default), gem5 uses a BreakPCEvent to provide a debugger hook into the simulator when the kernel crashes. This hook unconditionally kills gem5 with a SIGTRAP unless gem5 is compiled in fast mode. This is undesirable since the panic_on_panic param already provides similar functionality.
