nbd-client: do not leave child processes in the zombie state

Change SIGCHLD handler to SIG_DFL with SA_NOCLDWAIT flag set, to avoid
transforming child processes into zombies when they terminate.  Since
the main process is inevitably blocked in NBD_DO_IT ioctl at the time
when child processes terminate, this is the simplest way to get rid of
zombie processes.
