  Log Message:
  -----------
  system-ovn.at: Fix flaky "load-balancing" test.

When running load-balancing test, tcpdump is executed in background.
When the backround tcpdump stops, it sends to stderr a message
(such as number of packets captured) which might be catched by the
following command (wget) causing the test to fail.
