kernel-install: fix initramfs copying scripts
Fix current EFI boot dir discovery script.

Also, adjust scripts order:
50-dracut generates initramfs in /boot/(efi/)?/$MACHINE_ID/.../initrd
80-grub2 copies it to /boot/initramfs-....img
90-xen-efi copies it to /boot/efi/EFI/qubes/initramfs-....img

Make the above order explicit, rather than relying on xen sorted later
than grub2.
