commit ca05b754af74ab81525ff372f589ccfbc3ac81d9

    Fix incorrect file permissions of vmcore-dmesg-incomplete.txt

    vmcore-dmesg-incomplete.txt is generated by shell redirection,
    which taking the default umask value. When dmesg collector exits
    with non-zero, the file will exist and anyone can have access to
    it.

    This patch fixed the issue by chmod the file, making it accessible
    only to its owner.
