[PATCH v3 03/14] perf stat: Extend STD output linter to test basic New API checks

[Ian Rogers <irogers@google.com>]

This patch extends the standard console (STD) output linter script
tools/perf/tests/shell/stat+std_output.sh to run the basic no-argument
check a second time using the --new print flag:

  perf_cmd="--new -o ${stat_output}"
  check_no_args "STD (New API)" "$perf_cmd"

This ensures that standard console outputs produced by the decoupled
printing callbacks are formally validated by the test suite.
