ci/lava: Filter out undesired messages

Some LAVA jobs emit lots of messages "Listened to connection for
namespace 'common' for up to 1s" in a row at the end of the logs, making
difficult to see the result of the test script.

This commit removes those lines until a proper solution is deployed on
the LAVA side.

Closes: #6116
