ds: reap_pids: remove redundant signal blocking

Blocking signals when reaping was done when the lei pager was
spawned by the daemon in b90e8d6e02.  Shortly afterwards in
7b79c918a5, the client script took over spawning of the pager
and made b90e8d6e02 redundant.

    7b79c918a5 (lei: run pager in client script, 2021-01-10)
