fadump: use the original initrd to rebuild fadump initrdfrom

Browse Source 
The idea behind adding support for dracut '--rebuild' option was to
ensure the initrd built for fadump takes into consideration all the
build parameters passed to original initrd. Pass original initrd
instead of current default initrd for rebuild as current initrd
might already have build parameters from original initrd along
with parameters from previous fadump intird build making the
build parameters look like this after a few iterations:

-H --persistent-policy 'by-uuid' -f --quiet --hostonly --hostonly-
cmdline --hostonly-i18n --hostonly-mode 'strict' -o 'plymouth dash
resume ifcfg' --mount '/dev/mapper/rhel_zzfp219--lp3-home /kdumproot
//home xfs defaults' -f --kver '4.18.0-60.el8.ppc64le' --quiet
--hostonly --hostonly-cmdline --hostonly-i18n --hostonly-mode 'strict'
-o 'plymouth dash resume ifcfg' --mount '/dev/mapper/rhel_zzfp219--lp3-home
/kdumproot//home xfs defaults' -f --kver '4.18.0-60.el8.ppc64le' --quiet
--hostonly --hostonly-cmdline --hostonly-i18n --hostonly-mode 'strict'
-o 'plymouth dash resume ifcfg' --mount '/dev/mapper/rhel_zzfp219--lp3-home
/kdumproot//home xfs defaults' -f --kver '4.18.0-60.el8.ppc64le' --include
'/tmp/fadump.initramfs' '/etc/fadump.initramfs' --include
'/tmp/fadump.initramfs' '/etc/fadump.initramfs' --include
'/tmp/fadump.initramfs' '/etc/fadump.initramfs'
--

Since it is not desirable to build initrd with stale and/or  duplicate
build parameters, use original initrd (backed up) to rebuild fadump
initrd, instead of current default initrd.
