extable: Adjust system_state checks
To enable smp_processor_id() and might_sleep() debug checks earlier, it's required to add system states between SYSTEM_BOOTING and SYSTEM_RUNNING. Adjust the system_state check in core_kernel_text() to handle the extra states, i.e. to cover init text up to the point where the system switches to state RUNNING.
