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.

fadump: isolate fadump initramfs image within the default one
In case of fadump, the initramfs image has to be built to boot into
the production environment as well as to offload the active crash dump
to the specified dump target (for boot after crash). As the same image
would be used for both boot scenarios, it could not be built optimally
while accommodating both cases.
Use --include to include the initramfs image built for offloading
active crash dump to the specified dump target. Also, introduce a new
out-of-tree dracut module (99zz-fadumpinit) that installs a customized
init program while moving the default /init to /init.dracut. This
customized init program is leveraged to isolate fadump image within
the default initramfs image by kicking off default boot process
(exec /init.dracut) for regular boot scenario and activating fadump
initramfs image, if the system is booting after a crash.
If squash is available, ensure default initramfs image is also built
with squash module to reduce memory consumption in capture kernel.
