lib/storage: increase the number of created time series in BenchmarkHeadPostingForMatchers in order to be on par with Promethues

Browse source 
The previous commit was accidentally creating 10x smaller number of time series than Prometheus
and this led to invalid benchmark results.

The updated benchmark results:

VictoriaMetrics uses 1GB of RAM during the benchmark (vs 3.5GB of RAM for Prometheus)
