[PATCH v1] perf test: Stat std output match 2 metrics for stalled-cycles-backend

[Ian Rogers <irogers@google.com>]

Seen on ARM, the stalled-cycles-backend event can be given as the
event for both backend_cycles_idle and stalled_cycles_per_instruction
metrics. Make the metric match sufficiently generic to allow this.
