grubby-bls: print the absolute kernel and initramfs images paths

Browse Source 
The BLS file "linux" and "initrd" fields expect a relative paths from the
root of the partition that contains the kernel and initramfs. The grubby
tool was printing the value of thse fields and not their full path.

So if there is a partition and /boot is a mount point, he BLS would have:

linux /vmlinuz-4.18.0-38.el8.x86_64
initrd /initramfs-4.18.0-38.el8.x86_64.img

And grubby would print:

kernel="/vmlinuz-4.18.0-38.el8.x86_64"
initrd="/initramfs-4.18.0-38.el8.x86_64.img"

But the old tool used to print the full paths of the images, so should be:

kernel="/boot/vmlinuz-4.18.0-38.el8.x86_64"
initrd="/boot/initramfs-4.18.0-38.el8.x86_64.img"

Resolves: rhbz#1649778
