bpf: export bpf_sock for BPF_PROG_TYPE_SOCK_OPS prog type
And let it use bpf_sk_storage_{get,delete} helpers to access socket
storage. Kernel context (struct bpf_sock_ops_kern) already has sk
member, so I just expose it to the BPF hooks. I use
PTR_TO_SOCKET_OR_NULL and return NULL in !is_fullsock case.
I also export bpf_tcp_sock to make it possible to access tcp socket stats.
