does not create compressed dump on 5.0 or later kernels

Bug description:
[Impact]
On ppc64el, makedumpfile won't create compressed dumps, causing them to be
very large. This affects any kernel later than 4.19 actually.
[Test case]
Crash a system with kdump-tools installed and enabled, by using the following
sequence. Verify the created dumps are compressed by using file. This is the
same test as the autopkgtest for makedumpfile.
echo 1 | sudo tee /proc/sys/kernel/sysrq
echo c | sudo tee /proc/sysrq-trigger
[Regression potential]
This is a small fix and should only impact ppc64el. Older kernels should
still work, and should be tested.
