Arnaldo Carvalho de Melo 1ebe7d40ed perf bench: Add missing setlocale() call to allow usage of %'d style formatting ...

[ Upstream commit 16203e9cd0 ]

Without this we were not getting the thousands separator for big
numbers.

Noticed while developing 'perf bench uprobe', but the use of %' predates
that, for instance 'perf bench syscall' uses it.

Before:

  # perf bench uprobe all
  # Running uprobe/baseline benchmark...
  # Executed 1000 usleep(1000) calls
       Total time: 1054082243ns

   1054082.243000 nsecs/op

  #

After:

  # perf bench uprobe all
  # Running uprobe/baseline benchmark...
  # Executed 1,000 usleep(1000) calls
       Total time: 1,053,715,144ns

   1,053,715.144000 nsecs/op
