        fadump: kdumpctl should check the modules used by the fadump initramfs
    
        After fadump embedded the fadump initramfs in the normal initramfs,
        kdumpctl will mistakenly rebuild the initramfs everytime.
    
        kdumpctl checks the hostonly-kernel-modules.txt file in initramfs
        to check if required drivers are included, but the normal initramfs
        is built in non-hostonly mode, so it doesn't have a
        hostonly-kernel-modules.txt file. The check will always fail.
    
        So let mkfadumprd make a copy of the hostonly-kernel-modules.txt in the
        fadump initramfs and let kdumpctl check that file instead.
