unshare: don't try to reset the disposition of SIGKILL

If the child process is killed with SIGKILL, don't attempt to reset the
disposition of SIGKILL (which can't be caught or ignored anyway) before
self-signalling. This caused a misleading 'sigprocmask unblock failed'
error instead of dying with the same SIGKILL status as the child.
