[RFC PATCH v1 06/14] perf stat: Extend STD output linter to test metric-only checks

[Ian Rogers]

This patch extends tools/perf/tests/shell/stat+std_output.sh to run
the metric-only check under the --new print flag:

  - check_metric_only

This guarantees that standard console metric-only outputs produced by
the decoupled printing callbacks are formally validated by the test linter.
