mdcheck: make sure signals are processed immediately

"systemctl stop mdcheck_start.service" may hang for a long time,
because the shell doesn't handle signals until the sleep process in
the foreground returns. Fix this by starting sleep in the background
and waiting for it (the built-in "wait" receives the signal).
