perf trace: Wire up the fadvise 'advice' table generator

That ends up generating this:

  $ cat /tmp/build/perf/trace/beauty/generated/fadvise_advice_array.c
  static const char *fadvise_advices[] = {
	[0] = "NORMAL",
	[1] = "RANDOM",
	[2] = "SEQUENTIAL",
	[3] = "WILLNEED",
	[4] = "DONTNEED",
	[5] = "NOREUSE",
  };
