    Add tab key as delimiter for core_collector in kdump.conf
    
    In kdump.conf, space key is used as delimiter by default.
    
    In kdump_install_conf of dracut-module-setup.sh, if specify
    core_collector with a tab delimiter, the tool may not be
    copied into kdump-initrd.
    E.g, core_collector scp		-v
    
    And in dump_ssh of dracut-kdump.sh, dumping will fail caused
    by tab key in core_collector.
    
    Here change code to allow tab key as delimiter when specifying
    core_collector.
