DBTablePropertiesTest often times out in internal test infra (#7639)

Summary:
In this test, after flushing memtable, it will read directly from the sst files, so `env_do_fsync` was `true` to ensure that the flushed sst files can be read afterwards. Considering that the test does not last long, the data should be available in os buffer even without fsync, so this PR tries to disable fsync to reduce test time.

Test Plan: watch the test to pass in internal infra
