Vendor domains may use net_domain() so it should be moved to public
policy. This will allow removal of permissions such as rawip_socket
in future releases without breaking Treble compatiblity.

Test: build

Grant access to icmp_socket to netdomain. This was previously
labeled as rawip_socket which apps are allowed to use. Neverallow
all other new socket types for apps.
Kernels versions > 4.9 redefine ICMP sockets from rawip_socket
to icmp_socket. To pass neverallow tests, we need to define
which IOCTLs are allowed (and disallowed).
Note that this does not change behavior on devices with
kernel versions <=4.9. However, it is necessary (although not
sufficient) to pass CTS on kernel version 4.14.

Test: Grant icmp_socket in net.te and build.

This leaves only the existence of netdomain attribute as public API.
All other rules are implementation details of this attribute's policy
and are thus now private.
Test: No change to policy according to sesearch, except for
disappearance of all allow rules to do with netdomain_current
and *_current attributes targeted when netdomain rules reference
public types.
