tools/bpf: add ksym_get_addr() in trace_helpers
Given a kernel function name, ksym_get_addr() will return the kernel address for this function, or 0 if it cannot find this function name in /proc/kallsyms. This function will be used later when a kernel address is used to initiate a kprobe perf event.
