kernel-2.eclass: avoid lexicographical compare on versions, bug #705246

Originally found in bug #705240 as:

```
if [[ ... || ${KV_MAJOR}.${KV_MINOR}.${KV_PATCH} > 2.6.28 ]]; then
```

'>' are string comparisons. They are benign so far, but
will start failing on linux-10 :)

Let's be consistent and use version comparison.
