perf tests: Speed up metrics checking shell tests
Optimize the execution of the metric validation and metric listing shell
test suites:
1. `stat_metrics_values.sh`:
The Python metric validator runs the `perf bench futex hash` workload
for each validated metric relationship. Reduce the benchmark runtime
limit from `-r 2` (2 seconds) to `-r 1` (1 second). This cuts the
workload duration in half while still generating sufficient PMU events
to satisfy non-zero threshold metric validations.
2. `stat_all_metrics.sh`:
The metric checking test runs `perf stat` sequentially across all
433+ listed metrics. Change the default workload for system-wide runs
from `sleep 0.01` to `true`. This avoids the 10ms sleep delay on each
sequential metric invocation, saving over 4 seconds of total wall
time during full test suite runs.
