tracing: have function trace select kallsyms
Impact: fix output of function tracer to be useful The function tracer is pretty useless if KALLSYMS is not configured. Unless you are good at reading hex values, the function tracer should select the KALLSYMS configuration. Also, the dynamic function tracer will fail its self test if KALLSYMS is not selected.

This special tracer records the maximum stack footprint of the
kernel and displays it in debugfs/tracing/stack_trace.
