bpf: Add skb->sk, bpf_sk_fullsock and bpf_tcp_sock tests to test_verifer

Browse source

This patch tests accessing the skb->sk and the new helpers,
bpf_sk_fullsock and bpf_tcp_sock.

The errstr of some existing "reference tracking" tests is changed
with s/bpf_sock/sock/ and s/socket/sock/ where "sock" is from the
verifier's reg_type_str[].
