Breno Leitao 3dc6c76391 selftests: net: Add IPv6 support to netconsole basic tests
Add IPv6 support to the netconsole basic functionality tests by:

- Introducing separate IPv4 and IPv6 address variables (SRCIP4/SRCIP6,
  DSTIP4/DSTIP6) to replace the single SRCIP/DSTIP variables
- Adding select_ipv4_or_ipv6() function to choose protocol version
- Updating socat configuration to use UDP6-LISTEN for IPv6 tests
- Adding wait_for_port() wrapper to handle protocol-specific port waiting
- Expanding test matrix to run both basic and extended formats against
  both IPv4 and IPv6 protocols
- Improving cleanup to kill any remaining socat processes
- Adding sleep delays for better IPv6 packet handling reliability

The test now validates netconsole functionality across both IP versions,
improving test coverage for dual-stack network environments.

This test would avoid the regression fixed by commit f599020702 ("net:
netpoll: Initialize UDP checksum field before checksumming")
