kdumpctl: Remove slub_debug from cmdline

Browse Source 
slub_debug parameter enables debug for slub, making each object take
more memory than normal. During a typical kdump, "slub_debug=FZPU" will
cost about 33MB additional memory. If users really want to enable this
parameter, they should specify it in KDUMP_COMMANDLINE_APPEND.
