Subject: [PATCH net] selftests: netconsole: Increase port listening timeout

wait_for_port() can wait up to 2 seconds with the sleep and the polling
in wait_local_port_listen() combined. So, in netcons_basic.sh, the socat
process could die before the test writes to the netconsole.

Increase the timeout to 3 seconds to make netcons_basic.sh pass
consistently.

Fixes: 3dc6c76391cb ("selftests: net: Add IPv6 support to netconsole basic tests")
