kexec: lengthen the kernel command line image

The crash kernel's boot command line is not long enough to contain the
necessary memmap= options for a large memory.

The fix is simple, as long as the boot loader's command line is also long enough.
I'm not sure about boot loader or kernel restrictions to this length.
