Extend the scope of #ifndef LOCORE to also cover the prototype of ktr_tracepoint() and the macros using it. This allows this header to be included in .S files for obtaining the KTR_* class macros directly and providing a default value for KTR_COMPILE in case it's not specified in the kernel config file including defining it to 0 when not using 'options KTR' at all.
