bpf: Change bpf_setsockopt(SOL_SOCKET) to reuse sk_setsockopt()
After the prep work in the previous patches,
this patch removes most of the dup code from bpf_setsockopt(SOL_SOCKET)
and reuses them from sk_setsockopt().
The sock ptr test is added to the SO_RCVLOWAT because
the sk->sk_socket could be NULL in some of the bpf hooks.
The existing optname white-list is refactored into a new
function sol_socket_setsockopt().
