tcp: Generalise probing for tcpi_snd_wnd field
In order to use the tcpi_snd_wnd field from the TCP_INFO getsockopt() we
need the field to be supported in the runtime kernel (snd_wnd_cap).
In fact we should check that for for every tcp_info field we want to use,
beyond the very old ones shared with BSD. Prepare to do that, by
generalising the probing from setting a single bool to instead record the
size of the returned TCP_INFO structure. We can then use that recorded
value to check for the presence of any field we need.
