selftests/net: Fixes psock_fanout CBPF test case
'psock_fanout' has been failing since commit 4d7b9dc1 ("tools: psock_lib: harden socket filter used by psock tests"). That commit changed the CBPF filter to examine the full ethernet frame, and was tested on 'psock_tpacket' which uses SOCK_RAW. But 'psock_fanout' was also using this same CBPF in two places, for filtering and fanout, on a SOCK_DGRAM socket. Change 'psock_fanout' to use SOCK_RAW so that the CBPF program used with SO_ATTACH_FILTER can examine the entire frame. Create a new CBPF program for use with PACKET_FANOUT_DATA which ignores the header, as it cannot see the ethernet header. Tested: Ran tools/testing/selftests/net/psock_{fanout,tpacket} 10 times, and they all passed.
