lxc_spawn: initialize netpipe

When rebooting an unprivileged container, netpipe starts out as not -1. If count_veths somehow changed this could lead to trying to send data over nonexistent pipe. (Ok can't *really* happen, as it currently stands, but it's an open end) Signed-off-by: Serge Hallyn <serge.hallyn@ubuntu.com>
