The fetchlimit test depends on a resolver continuing to try UDP and timing out while the client waits for resolution to succeed. but since commitbb990030(flag day 2020), a fetch will always switch to TCP after two timeouts, unless EDNS was disabled for the query. This commit adds "edns no;" to server statements in the fetchlimit resolver, to restore the behavior expected by the test. (cherry picked from commit81deb24deb)
