Change pkglist perms to 644

- I wanted to have them at 600 because I thought that it might be a problem if everyone can read which packages were installed since the start.
- 644 is kind of logical though because one could at least see the currently installed packages and their versions anyways and I don't think that it's actually a big issue anyways.
