This removes some noise that can be distracting while looking at selftests by redirecting socat stderr to /dev/null.

Before this commit, netcons_basic would output:

Running with target mode: basic (ipv6) 2025/11/29 12:08:03 socat[259] W exiting on signal 15 2025/11/29 12:08:03 socat[271] W exiting on signal 15 basic : ipv6 : Test passed Running with target mode: basic (ipv4) 2025/11/29 12:08:05 socat[329] W exiting on signal 15 2025/11/29 12:08:05 socat[322] W exiting on signal 15 basic : ipv4 : Test passed Running with target mode: extended (ipv6) 2025/11/29 12:08:08 socat[386] W exiting on signal 15 2025/11/29 12:08:08 socat[386] W exiting on signal 15 2025/11/29 12:08:08 socat[380] W exiting on signal 15 extended : ipv6 : Test passed Running with target mode: extended (ipv4) 2025/11/29 12:08:10 socat[440] W exiting on signal 15 2025/11/29 12:08:10 socat[435] W exiting on signal 15 2025/11/29 12:08:10 socat[435] W exiting on signal 15 extended : ipv4 : Test passed

After these changes, output looks like:

Running with target mode: basic (ipv6) basic : ipv6 : Test passed Running with target mode: basic (ipv4) basic : ipv4 : Test passed Running with target mode: extended (ipv6) extended : ipv6 : Test passed Running with target mode: extended (ipv4) extended : ipv4 : Test passed
