test: allow no vectored gets happening (#7939)

Browse Source 
when running the regress tests locally without any environment variables
we use on CI, `test_pageserver_compaction_smoke` fails with division by
zero. fix it temporarily by allowing no vectored read happening. to be
cleaned when vectored get validation gets removed and the default value
can be changed.
