Do not allow stream socket retries in libkrad

Before this patch, libkrad would follow the same exact logic for all
socket types when the retries parameter was non-zero.  This meant that
when connecting with SOCK_STREAM, multiple requests were sent in case
of packet drops, which, of course, cannot happen for SOCK_STREAM.

Instead, just disable retries for SOCK_STREAM sockets.
