perf beauty: Add generator for fadvise64's 'advice' arg constants 

$ tools/perf/trace/beauty/fadvise.sh
  static const char *fadvise_advices[] = {
	[0] = "NORMAL",
	[1] = "RANDOM",
	[2] = "SEQUENTIAL",
	[3] = "WILLNEED",
	[4] = "DONTNEED",
	[5] = "NOREUSE",
  };
  $

This has a hack wrt the s390 difference.

# XXX Fix this properly:
# The grep 6/7 DONTNEED/NOREUSE are a hack to filter out the s/390 oddity See
# tools/include/uapi/linux/fadvise.h for details.
# Probably fix this when generating the string tables per arch so that We can
# reliably process on arch FOO a perf.data file collected by 'perf trace
# record' on arch BAR, e.g. collect on s/390 and process on x86.
