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

Commit a985442fde ("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.
