Hey Guys.

This is my first time filing a bug, and I'm not 100% sure it is one, so
forgive the ignorance if I'm missing something.

I just installed CentOS 7, ran all the updates, and ran "grub2-mkconfig" to
generate a new grub menu, but the list of kernels does not appear to be in
proper order.

This appears to be caused by grub-mkconfig_lib's version_find_latest function
not returning the proper newest kernel.

Attached is my short test script, using the grub-mkconfig_lib library from the
latest commit (0901e7855f922e770cbfeb58262cb8fded518190).

This is the output I get from my script:

        Original List:
        /boot/vmlinuz-0-rescue-ee3529f5964c4439921a155f7fd766e7
        /boot/vmlinuz-3.10.0-123.4.2.el7.x86_64
        /boot/vmlinuz-3.10.0-123.el7.x86_64

        Sorted List:
        /boot/vmlinuz-3.10.0-123.el7.x86_64
        /boot/vmlinuz-3.10.0-123.4.2.el7.x86_64
        /boot/vmlinuz-0-rescue-ee3529f5964c4439921a155f7fd766e7

Unless I am mistaken, kernel vmlinuz-3.10.0-123.el7.x86_64 is older than
vmlinuz-3.10.0-123.4.2.el7.x86_64, and should appear lower in the list.
Am I missing something or is this a bug?
