kdump.sysconfig.ppc64(le): remove "root=" param from ppc64(le) 2nd kernel's command line

Browse Source 
For ppc64(le), the default behavior of kexec always copy "root=" param,
but if dump target is ssh, there will no tools installed in kdump
rd, which help to mount root. As a result, kdump service will fail to
start. So explicitly disable the default behavior with --dt_no_old_root
option.
