selftests/net: Fixes psock_fanout CBPF test case
'psock_fanout' has been failing since commit 4d7b9dc1f36a9 ("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.
Fixes: 4d7b9dc1f36a9 ("tools: psock_lib: harden socket filter used by psock tests")
