test_runner: tweak test_create_snapshot compaction (#11495)

Browse Source 
## Problem

With the recent improvements to L0 compaction responsiveness,
`test_create_snapshot` now ends up generating 10,000 layer files
(compared to 1,000 in previous snapshots). This increases the snapshot
size by 4x, and significantly slows down tests.

## Summary of changes

Increase the target layer size from 128 KB to 256 KB, and the L0
compaction threshold from 1 to 5. This reduces the layer count from
about 10,000 to 1,000.
