Test that applications binding listening sockets to VRFs without
specifying TCP_MD5SIG_FLAG_IFINDEX will work as expected. This would
be broken if __tcp_md5_do_lookup always made a strict comparison on
l3index. See this email:

Applications using tcp_l3mdev_accept=1 and a single global socket (not
bound to any interface) also should have a way to specify keys that are
only for the default VRF, this is done by --do-bind-key-ifindex without
otherwise binding to a device.
