James Clark 65319890c3 perf tools: Fix "kernel lock contention analysis" test by not printing warnings in quiet mode 
Especially when CONFIG_LOCKDEP and other debug configs are enabled,
Perf can print the following warning when running the "kernel lock
contention analysis" test:

  Warning:
  Processed 1378918 events and lost 4 chunks!

  Check IO/CPU overload!

  Warning:
  Processed 4593325 samples and lost 70.00%!

The test already supplies -q to run in quiet mode, so extend quiet mode
to perf_stdio__warning() and also ui__warning() for consistency.

This fixes the following failure due to the extra lines counted:

  perf test "lock cont" -vvv

  82: kernel lock contention analysis test                            :
  --- start ---
  test child forked, pid 3125
  Testing perf lock record and perf lock contention
  [Fail] Recorded result count is not 1: 9
  test child finished with -1
  ---- end ----
  kernel lock contention analysis test: FAILED!
