wget: fix for brain-damaged HTTP servers. Closes 9471

write(3, "GET / HTTP/1.1\r\nUser-Agent: Wget\r\nConnection: close\r\n\r\n", 74) = 74
shutdown(3, SHUT_WR)    = 0
alarm(900)              = 900
read(3, "", 1024)       = 0
write(2, "wget: error getting response\n", 29) = 29
exit(1)

The peer simply does not return anything. It closes its connection.

Probably it detects wget closing its writing end: shutdown(3, SHUT_WR).

The point it, closing write side of the socket is _valid_ for HTTP.
wget sent the full request, it won't be sending anything more:
it will only receive the response, and that's it.
