perf test: Remove x permission from lib/stat_output.sh

The commit fc51fc87b1b8 factored out the helper functions to a library
but the new file had execute permission.  Due to the way it detects
the shell test scripts, it showed up in the perf test list unexpectedly.

  $ ./perf test list 2>&1 | grep 86
   76: x86 bp modify
   77: x86 Sample parsing
   78: x86 hybrid
   86:                        <---- (here)

  $ ./perf test -v 86
   86:                                                                 :
  --- start ---
  test child forked, pid 1932207
  test child finished with 0
  ---- end ----
  : Ok

As it's a collection of library functions, it should not run as is.
Let's remove the execute permission.
