Small fix for Kernel.pm

Noticed an issue on my machine with the kernel checks. It claimed that I wasn't running the latest kernel, but that it was installed and recommended a reboot. It didn't go away after the reboot and I found it was due to ".x86_64" at the end of the string. I added 1 line that fixes that and doesn't seem to cause an issue. Please ignore the two test commits, I was having a small issue with git.
