James Clark ad73216e00 perf test: Remove bash construct from stat_bpf_counters.sh test

[ Upstream commit c8b947642d2339ce74c6a1ce56726089539f48d9 ]

Currently the test skips with an error because == only works in bash:

  $ ./perf test 91 -v
  Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
  91: perf stat --bpf-counters test                                   :
  --- start ---
  test child forked, pid 44586
  ./tests/shell/stat_bpf_counters.sh: 26: [: -v: unexpected operator
  test child finished with -2
  ---- end ----
  perf stat --bpf-counters test: Skip

Changing == to = does the same thing, but doesn't result in an error:

  ./perf test 91 -v
  Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
  91: perf stat --bpf-counters test                                   :
  --- start ---
  test child forked, pid 45833
  Skipping: --bpf-counters not supported
    Error: unknown option `bpf-counters'
  [...]
  test child finished with -2
  ---- end ----
  perf stat --bpf-counters test: Skip
