Peter Dillinger 80ac7412b5 Polish/deflake BackupEngineTest.FileCollision (#9257) 
Summary:
Use smaller and more predictable behaviors

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9257

Test Plan:
gtest-parallel --repeat=N ./backupable_db_test --gtest_filter=BackupEngineTest.FileCollision

before (N=50) we see inconsistent sets of SST files

    $ find /dev/shm/rocksdb_blah/ | grep -o '/00.*sst' | grep -o '^[^_]*' | sort | uniq -c
     49 /000009
      3 /000010
      1 /000010.sst
     49 /000012
      3 /000013
      1 /000013.sst
     49 /000015
      2 /000016
      1 /000016.sst
     22 /000018
      2 /000019
      1 /000019.sst
     29 /000020
     11 /000021
      2 /000021.sst
     46 /000022
      2 /000022.sst
      4 /000023
      1 /000023.sst
     27 /000025

And after (N=5000) we see

    $ find /dev/shm/rocksdb_blah/ | grep -o '/00.*sst' | grep -o '^[^_]*' | sort | uniq -c
      10000 /000009
      10000 /000012
       5000 /000015
