perf parse-events: Avoid enum forward declaration.

Enum forward declarations aren't allowed as the size can't be implied.
Switch to just using an int. This fixes a clang warning:

  In file included from tools/perf/bench/evlist-open-close.c:13:

  enum perf_tool_event;
       ^
  tools/perf/bench/../util/evsel.h:28:6: note: previous definition is here
  enum perf_tool_event {
