kernel: add kernel version matching code for opensuse

The current code for checking if the running kernel version matches the
most recent kernel version in the repos does not work on opensuse when
"-k distro" is given.

This commit adds an opensuse-specific codepath with a version match
check that works in the opensuse testing environment.
