The grub-btrfs snapshot detection was in guided.py, forcing custom script authors to replicate it. Since Installer already holds disk_config, the check belongs inside add_bootloader().

Fixes #4505
When UKI and Grub are used together with btrfs snapshots (Snapper or Timeshift), _config_uki() no longer comments out *_image= lines in mkinitcpio presets and no longer deletes initramfs files. This lets mkinitcpio -P generate both UKI and standalone initramfs, so grub-btrfs can find initramfs-linux.img for snapshot boot entries.
Without this fix, _config_uki() unconditionally disables standalone initramfs generation, leaving grub-btrfs without a bootable kernel image for snapshots.
