Subject: [PATCH] perf stat: Fix recort_usage typo

Markus reported gcc 6 complains when compiling perf stat command:

  builtin-stat.c:1591:27: error: ‘recort_usage’ defined but not used
  [-Werror=unused-const-variable]
   static const char * const recort_usage[] = {
                             ^~~~~~~~~~~~
I fixed the typo and realized we already export record_usage,
so I also prefixed it with stat (and included report_usage).
