[PATCH V2 2/3] kdumpctl: force rebuild in case of dynamic system modification

[Pratyush Anand]

There could be some dynamic system modification, which may affect kdump
kernel boot process. In such situation initramfs must be rebulit on the
basis of changes.
Since most of these checking methods will use information from
TARGET_INITRD, therefore check for its existence in common code.
