Removin unneeded packages
configs/releng/packages.x86_64: Removing packages:
- grub :rescue/ installation actions for grub should be run from within a chroot
- lsscsi: lsblk provides the same functionality
- netctl: we have systemd-networkd enabled by default
- ntp: we have systemd-timesyncd
- refind: rescue/ installation actions for refind should be run from within a chroot
- vi: we have vim
Closes #15 (closed)
