More fixes for BLS 
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.

Subject: [PATCH 014/243] mkimage: Pass layout to mkimage_generate_elfXX rather
than some fields.
This allows easier extension of this function without having too long of
arguments list.
