  3. 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.

  5. crashkernel: Add ttyS0 console 

    Add "console=ttyS0,115200n8" to crashkernel commandline as we did for
the regular kernel in mxgrub. Also specifiy full command line here
instead of appending to the command line of the crashing kernel to get a
better defined state.
