Speed up BenchmarkPostings_Stats (#9213) 
The previous code re-used series IDs 1-1000 many times over, so a lot
of time was spent ensuring the lists of series were in ascending order.
The intended use of `MemPostings.Add()` is that all series IDs are
unique, and changing the benchmark to do this lets it finish ten times
faster.

(It doesn't affect the benchmark result, just the setup code)
