main/unl0kr: introduce subpackage for the fb_force_refresh quirk, make packages depend on it, and add it as dep to generic-x86_64

A surprinsingly amount of devices use this quirk. So instead of having each of those packages package the file individually, let's create a single unl0kr subpackage that they can depend on.

I also "sneaked in" a dependency to generic-x86_64.

I believe this also makes the whole thing more maintainable. In the next unl0kr release, we can and should move this file to /usr/share, which will be a lot simpler if it's just in one place
