perf tests: Remove bash constructs from stat_all_pmu.sh

The tests were passing but without testing and were printing the
following:

  $ ./perf test -v 90
  90: perf all PMU test                                               :
  --- start ---
  test child forked, pid 51650
  Testing cpu/branch-instructions/
  ./tests/shell/stat_all_pmu.sh: 10: [:
   Performance counter stats for 'true':

             137,307      cpu/branch-instructions/

         0.001686672 seconds time elapsed

         0.001376000 seconds user
         0.000000000 seconds sys: unexpected operator

Changing the regexes to a grep works in sh and prints this:

  $ ./perf test -v 90
  90: perf all PMU test                                               :
  --- start ---
  test child forked, pid 60186
  [...]
  Testing tlb_flush.stlb_any
  test child finished with 0
  ---- end ----
  perf all PMU test: Ok
