Add support for IPv6 environment for napi_id test.
Test Plan:
./run_kselftest.sh -t drivers/net:napi_id.py
TAP version 13
1..1
# timeout set to 45
# selftests: drivers/net: napi_id.py
# TAP version 13
# 1..1
# ok 1 napi_id.test_napi_id
# # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0
ok 1 selftests: drivers/net: napi_id.py
