gh-154303: Skip test_sqlite3 CLI completion tests on OpenBSD (GH-154304)

OpenBSD's readline does not honor "completion-query-items 0", so completing
many candidates blocks on a "Display all N?" prompt that hangs the
pseudo-terminal opened by run_pty().  Skip the whole Completion class on
OpenBSD, like the existing libedit skip.
