The datagram_channel::send() method that sends net::packet-s is
deprecated in favor of using span<temporary_buffer> one. Auditing code
still uses the former one -- it constructs a packet by using formatted
string by copying the string into the packet's fragment, then sends it.
This patch releases string into temporary_buffer and then passes
one-element span to send().
