Fix test in LITE mode (#6267) 

Summary:
Currently, the recently-added test DBTest2.SwitchMemtableRaceWithNewManifest
fails in LITE mode since SetOptions() returns "Not supported". I do not want to
put `#ifndef ROCKSDB_LITE` because it reduces test coverage. Instead, just
trigger compaction on a different column family. The bg compaction thread
calling LogAndApply() may race with thread calling SwitchMemtable().

Test Plan (dev server):
make check
OPT=-DROCKSDB_LITE make check

or run DBTest2.SwitchMemtableRaceWithNewManifest 100 times.
