[BUG] stream_sock: always shutdown(SHUT_WR) before closing

When we close a socket with unread data in the buffer, or when the
nolinger option is set, we regularly lose the last fragment, which
often contains the error message. This typically occurs when sending
too large a request. Only the RST is seen due to the close() (since
not all data were read) and the output message never reaches the
network.

Doing a shutdown() before the close() solves this annoying issue
because the data are really pushed before the system sends the RST.
