Revert "Fix Debian init script's "stop" action"

This reverts commit 4b1bd2292f087af5dfaf36b88569adbbea514b1d.

My apologies to start-stop-daemon as it works just fine, but it was a
Repose packaging bug that kept the init script from stopping Repose
(immediately after upgrading Repose and installing Java 7 when
/proc/${PID}/exe of the still-running Repose doesn't point to the
/usr/bin/java of the new Java 7 package).
