    mkdumprd: Fix makedumpfile parameter check.

    If only "makedumpfile" is written in "core_collector" of /etc/kdump.conf
    and try to run makedumpfile without options,
    "makedumpfile --check-params" fails and terminates abnormally.

        # grep ^core_collector /etc/kdump.conf
        core_collector makedumpfile
        # /usr/bin/kdumpctl start
        :
        Commandline parameter is invalid.
        Try `makedumpfile --help' for more information.
        kdump: makedumpfile parameter check failed.
        kdump: mkdumprd: failed to make kdump initrd
        kdump: Starting kdump: [FAILED]

    On the other hand, "makedumpfile --check-params" works fine without any options.

        # makedumpfile --check-params vmcore dumpfile
        # echo $?
        0

    In addition, before verify_core_collector() was implemented,
    initial RAM for kdump was successfully created using only "core_collector makedumpfile".
    I consider it a regression.

    This is due to a parameter extraction error in verify_core_collector().
    Fix it to correctly extract only the options as follows.
