Resolves: RHEL-49590
Upstream: https://github.com/rhkdump/kdump-utils
Conflict: Yes, kexec-tools is split into 3 parts upstream, some changes should
be applied to kdump-utils Makefile, but RHEL-9 kexec-tools doesn't have that.
Also missing upstream commits:
- 1732a3b(mkdumprd: Omit rdma module)
- 7fec2f56(mkdumprd: simplify handling of dracut arguments)

Add kdump dracut config
In some cases, customizing the first kernel's initrd is necessary by
modifying the dracut `omit_dracutmodules` options, such as in Bootc
or CoreOS scenarios [1]. However, these changes can unintentionally
break existing functionality in kdump. For instance, setting
`omit_dracutmodules='nfs'` prevents the `nfs` module from being added.
Additionally, some dracut configurations [2] use
`dracutmodules+='some modules'` instead of
`add_dracutmodules+='some modules'`. When `dracutmodules` is non-empty,
dracut includes only the specified modules, which can result in an
initrd that lacks necessary modules, causing kdump to fail.
Dracut upstream support --add-confdir now, kdump can use this
option when building kdump initramfs.
This patch moved the hardcoded dracutmodules from mkdumprd to the new
conf file /lib/kdump/dracut.conf.d/99-kdump.conf, it is easier to check
and modify to omit or add certain modules. This patch also initialize
dracutmodules to empty to avoid the influence of other configurations.
