Under Windows, utilities stored in the 'libexec' installation path are
installed in the executable path. They usually have a '5' suffix e.g.
kcookiejar5, ktelnetservices5, ktrash5.
kioslave is used by kio internally to start io slaves using klauncher.
This patch requires a similar patch to be applied to klauncher
(repo kinit, see https://phabricator.kde.org/D17719)
