Make sure we also downgrade from LEAP versions
Make sure we also downgrade from LEAP versions

We want to prioritize Pixelated packages over LEAP
ones. In a situation where there's already a LEAP
package installed with a higher version number,
we need to increase the apt pin priority from 1000
to 1001 which allowes a downgrade.

see https://github.com/pixelated/project-issues/issues/415
and `man apt_preferences`
