Michael Petlan 51433ead14 perf stat: Avoid segfaults caused by negated options
Some 'perf stat' options do not make sense to be negated (event,
cgroup), some do not have negated path implemented (metrics). Due to
that, it is better to disable the "no-" prefix for them, since
otherwise, the later opt-parsing segfaults.

Before:

  $ perf stat --no-metrics -- ls
  Segmentation fault (core dumped)

After:

  $ perf stat --no-metrics -- ls
   Error: option `no-metrics' isn't available
   Usage: perf stat [<options>] [<command>]
