selftests: net: switch to socat in the GSO GRE test

2021-11-13T03:59:01Z

Commit a985442fdecb ("selftests: net: properly support IPv6 in GSO GRE test") is not compatible with: Ncat: Version 7.80 ( https://nmap.org/ncat ) (which is distributed with Fedora/Red Hat), tests fail with: nc: invalid option -- 'N' Let's switch to socat which is far more dependable.

Explicitly pass -6 to netcat when the test is using IPv6 to prevent failures. Also make sure to pass "-N" to netcat to close the socket after EOF on the client side, otherwise we would always hit the timeout and the test would fail.
