Log Message:
Fix paths in two missed installed scripts.

The intention of zmsystemctl.pl is to use bin/pkexec to allow the apache user
to start and stop the ZoneMinder services on operating systems using systemd
and newer versions of Polkit than Pkgsrc currently has.

If the base OS doesn't use systemd (E.g. anything not Linux), this file
shouldn't be used anyway.

In Pkgsrc we ignore the potentially absent pkexec interpreter in this file.
If the base OS uses systemd, it probably also has pkexec in its base
installation.

Bump PKGREVISION.
