Tao Liu 004daebeff dracut-early-kdump-module-setup.sh: install xargs and kdump-lib-initramfs.sh
For earlykdump, kdump-lib-initramfs.sh is sourced by kdump-lib.sh,
however it is not installed in dracut-early-kdump-module-setup.sh. Same
as xargs, which is used by kdump-lib.sh. Otherwise earlykdump will report
file not found errors.

Fixes: a5faa052d4
       ("kdump-lib-initramfs.sh: prepare to be a POSIX compatible lib")
Fixes: 4f01cb1b0a
       ("kdump-lib.sh: fix variable quoting issue")
