selftests: Fix IPv6 address bind tests
[ Upstream commit 28a2686c185e84b6aa6a4d9c9a972360eb7ca266 ]
IPv6 allows binding a socket to a device then binding to an address
not on the device (__inet6_bind -> ipv6_chk_addr with strict flag
not set). Update the bind tests to reflect legacy behavior.
Fixes: 34d0302ab861 ("selftests: Add ipv6 address bind tests to fcnal-test")
