Subject: [PATCH] Fix LITE build with DBTest2.AutoPrefixMode1 (#6346)

Summary:
DBTest2.AutoPrefixMode1 doesn't pass because auto prefix mode is not supported there.
Fix it by disabling the test.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6346

Test Plan: Run DBTest2.AutoPrefixMode1 in lite mode

Differential Revision: D19627486
