Fact 637 add lsbminordistrelease

That's not correct though; given the Ubuntu release `10.04` the major version isn't actually `10`; it's `10.04` and `10.10` isn't a patch release to `10.04`. When Ubuntu does do a minor release of a distribution, they add it as the z part of x.y.z - for example `14.04.1` should have a minor release of `1`, not `4`.
