BUILD: cli/threads: fix build in single-threaded mode

Commit a8f57d51a ("MINOR: cli/activity: report the accept queue sizes
in "show activity"") broke the single-threaded build because the
accept-rings are not implemented there. Let's ifdef this out. Ideally
we should start to think about always having such elements initialized
even without threads to improve the test coverage.
