perf tools: Add missing struct definition in probe_event.h

Commit 0b3c226 ("perf symbols: Fix kallsyms perf test on ppc64le") refers struct symbol in probe_event.h, but forgets to include its definition. Gcc will complain about it when that definition is not added, by sheer luck, by some other header included before probe_event.h.
