tests: fix recent regression in tail inotify test

* tests/tail-2/inotify-rotate.sh (cleanup_fail_): Set fail=1
so that failures are identified.  Regression in v8.23-63-g111a2b9
Also use print_ver_ rather than open coding --verbose support.
Also check for more than a single 'b' which seems brittle.
