[PATCH 1/3] update kernel crashkernel in posttrans RPM scriptlet when updating kexec-tools

When doing in-place upgrading using leapp on x86_64, kdumpcl can't acquire instance lock when running in %post RPM scriplet on x86_64, localhost upgrade[1306]: /bin/kdumpctl: line 49: /var/lock/kdump: No such file or directory localhost upgrade[1306]: kdump: Create file lock failed and running "touch /var/lock/dkump" also fails with "No such file or directory". Thus kdumpctl can't be run in %post scriptlet. But kdumpctl can be run in %posttrans RPM scriplet. Besides, it's better to update crashkernel after the kernel has been updated. So let's update kernel crashkernel in the %posttrans scriptlet which will be run in the end of a transaction i.e. after the kernel has been updated. Note for %posttrans scriptlet, "$1 == 1" means both installing a new package and upgrading a package.
