classes: Rebase override_image_types_{ota,ostree}

- override_image_types_ostree.inc is no longer required;
- override_image_types_ota.inc is mostly superseded by upstream, except
  the creation of /boot/grub as a symlink to /boot/loader
  (note that /boot/grub2 is a real dir with /boot/grub2/grub.cfg being
  a symlink to /boot/loader/grub.cfg - it would be quite
  complicated to override the whole IMAGE_CMD_ota just to keep
  symlinking the parent dir instead of grub.cfg directly); /boot/grub
  should be a symlink so that /boot/grub/grubenv also points to
  /boot/loader/grubenv); fold its contents into
  enea-nfv-access-host-common.inc as it doesn't override a class anymore

Note: Previously, OSTree did not follow symlinks, so the symlink
      /boot/grub2/grub.cfg was being overwritten with a real file,
      this is no longer an issue.
