Redo preset call on upgrades

The preset was changed to 'enable', as part of
https://fedoraproject.org/wiki/Changes/EnableFwupdRefreshByDefault
(see https://bugzilla.redhat.com/show_bug.cgi?id=2236498).

To update existing systems on installations, this adds a trigger
scriptlet that will fire when upgrading from older releases to F39
or F40.
