[PATCH] ds: reap_pids: remove redundant signal blocking

[Eric Wong <e@80x24.org>]

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.

cf. b90e8d6e02 (ds: block signals when reaping, 2021-01-10)
    7b79c918a5 (lei: run pager in client script, 2021-01-10)
