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.
