kdump.sysconfig*: add ignition.firstboot to KDUMP_COMMANDLINE_REMOVE
For CoreOS based systems we use Ignition for provisioning machines
in the initramfs on first boot. We trigger Ignition right now by
the presence of `ignition.firstboot` in the kernel command line. The
kernel argument is only present on first boot so after a reboot it
no longer is in the kernel command line.
If a kernel crash happens before the first reboot of a machine we
want the `ignition.firstboot` kernel argument to be removed and not
passed on to the crash kernel.
