Subject: [PATCH] mxgrub: Do not use old command line on reboot

When we use `mxgrub --reboot` we don't want to reuse the previous kernel
command line.

Generate a new command line for kexec.

This way, changes we make to $KERNEL_PARAMETER in this script can be activated
by `mxgrub --reboot` as well.
