PackageKit: specify a cache-age otherwise it is infinite by default

[MatMaul]

Completely untested because I don't have a dev env to test but something like that should be enough to fix #23086 I believe.

We may want to add an init method directly on the PackageManager interface instead of doing what I did here. We can't do that in the constructor since we need an async context.

Not sure if this will work as SetHints seem to be for a created transaction. Maybe we can do something like this, will check

Indeed good catch thanks.

I've build some rpm for my server and I'll be able to test it on next available updates.
