fix(pageserver): ensure all layers are flushed before measuring RSS (#…
4630b70 
…9861)

## Problem

close #9761

The test assumed that no new L0 layers are flushed throughout the
process, which is not true.

## Summary of changes

Fix the test case `test_compaction_l0_memory` by flushing in-memory
layers before compaction.
