$NetBSD: patch-scripts_zmpkg_pl_in,v 1.2 2024/12/01 13:49:48 gdt Exp $

The systemd check in zmpkg.pl does not work, even on systems that use
systemd.  It fails to start, eventually timing out, if there is any
parent process between zmpkg.pl and systemd or init - such as
/etc/init.d/zoneminder.  But everything does seem to work ok from
systemd without this roundabout code anyway, so just inhibit it.

Add sleep to avoid suspected race condition.

\todo After catching up, actually debug and/or send upstream.
