nbd-server: fix signal handling

Reset SIGCHLD and SIGTERM handlers to SIG_DFL in child processes because
it is not their business to handle these signals.  Block SIGCHLD and
SIGTERM for the short time of fork, changing signal handlers and
changing "children" hash table to avoid race conditions with nasty
consequences.  Fix SIGTERM handler to always unlink pidfile.
