zdtm/static/sock_opts00: use unix socket to test SO_PASSCRED and SO_PASSSEC

Browse source 
SO_PASSCRED and SO_PASSSEC are only valid for AF_UNIX and AF_NETLINK
This patch updates the test logic to use a unix socket for these options,
while preserving the original value consistency check

Fixes: #2705
