kdump.conf: use a simple generator script to maintain

Browse Source 
This commit has the same motivation as the commit 677da8a "sysconfig:
use a simple generator script to maintain".

At present, only the kdump.conf generated for s390x has a slight
difference from the other arches, where the core_collector asks the
makedumpfile to use "-c" option to compress dump data by each page using
zlib, which is more efficient than lzo on s390x.
