Add some fixes for BLS parsing logic and also make 20-grub.install script to query the relative path of the kernel and initramfs images, so BLS can also work when /boot is not a mount point or is a btrfs subvolume. Also pull some build fixes. Resolves: rhbz#1588184 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>
