[PATCH 2/2 net-next v3] selftests: net: add ipv6 ping to local address from localhost

Test ipv6 pinging to local configured address and linklocal address from
localhost with -I ::1.

Signed-off-by: Fernando Fernandez Mancera <redacted>
---
v2: shellcheck fixes, added VRF based tests and simplified linklocal
address parsing
v3: extend existing test in fcnal-test.sh instead of creating a new one,
notice some shellcheck warnings but I prefer to follow the style of the
existing code. It can be fixed if it is a requirement.
