ext/dba/tests/dba_tcadb.phpt: fix expected output

Several of our DBA tests (based on setup/setup_dba_tests.inc) have a
"no lock" version whose expected output is,

  SAME OUTPUT AS PREVIOUS RUN (modulo read during write due to no lock)

This particular tokyocabinet test, however, is missing the "modulo"
bit, causing the lock-free test to fail. Comparing with, for example,
ext/dba/tests/dba_{flat,ini}file.phpt, it looks like the right thing
to do is simply to add it.
