cmake: link ceph_test_keyvaluedb directly against kv library

Fix incorrect transitive dependency by linking ceph_test_keyvaluedb
directly against the kv library instead of relying on transitive
linkage through the os library.

The test includes headers from kv/KeyValueDB.h and kv/RocksDBStore.h,
which are provided by the kv target, not os. This change makes the
dependency explicit and corrects the build configuration.
