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. Change-Id: I15548d830f8eff1fd4d64005c5769ca2be8d4ffe
