M. Vefa Bicakci 7e10236038 Update kexec-tools/makedumpfile to support v5.10 kernel
This patch updates kexec-tools from 2.0.15 to 2.0.21 (and its supporting
software package makedumpfile from 1.6.2 to 1.6.9) for compatibility
with the newer v5.10 kernel.

This commit clones the kexec-tools package's supporting files from
commit 26a7a543427eac59ed39728466f3d95d320f735a in the CentOS RPM
packaging git repository. Links for reference:

- 26a7a54342
- 26a7a54342

Please note that this patch causes the build system to pull in and
extract an SRPM file to acquire:
  kdump-anaconda-addon-003-29-g4c517c5.tar.gz

This is done for security, because the only public reference to commit
4c517c5 is on a Red Hat developer's personal Github account:
  https://github.com/ryncsn/kdump-anaconda-addon/commits/rhel-7

kexec-tools package's supporting files cloned by this commit trigger a
large number of shell script linting errors. Given that the shell
scripts in question are inherited from upstream (i.e., CentOS 7), the
"files" directory of this package is excluded from automated linting via
the changes in tox.ini.

Verification: A kexec-tools RPM package built with this commit was
installed onto an existing StarlingX system. A vmcore file was
succesfully collected from a kernel crash triggered with
/proc/sysrq-trigger. A recent version of the crash utility was found to
succesfully parse the collected vmcore file.

Credits: Thanks to Jiping Ma for helping with cleaning up and publishing
an earlier version of this patch.
