qspawn: clarify and improve error handling

EINTR should not happen when using non-blocking sockets like we
do in our daemons, but maybe some OSes allow it to happen and
edge-triggered notifications won't notify us again.

So always retry immediately on EINTR without relying on kqueue
or epoll to notify us, and log any other unrecoverable errors
which may happen while we're at it.
