Enforce ioctl command whitelisting on all sockets

Remove the ioctl permission for most socket types. For others, such as
tcp/udp/rawip/unix_dgram/unix_stream set a default unprivileged whitelist
that individual domains may extend (except where neverallowed like
untrusted_app). Enforce via a neverallowxperm rule.
