selftests: drv-net: xdp: run with both IP versions

Parameterize test cases by IP version using @ksft_variants. Set the
environment's IP version at the start of each case using a new local
helper, which also handles restoring the original value via defer().

The last case is left unparameterized because it does not send traffic
or exercise IP-version-specific code.

While here, fix an int vs str comparison bug `if cfg.addr_ipver == 4`.
