Subject: [PATCH v1] perf test parse-metric: Ensure aggregate counts appear to
 have run

Commit bb5a920b9099 ("perf stat: Ensure metrics are displayed even
with failed events") made it so that counters which weren't enabled in
the kernel were handled as NaN in metrics. This cased the "Parse and
process metrics" test to start failing as it wasn't putting a non-zero
value in these variables. Add arbitrary values of 1 to fix the test.

Fixes: bb5a920b9099 ("perf stat: Ensure metrics are displayed even with failed events")
