Virgil Dupras dd24cdc3d6 Fix incompatibility with LXC 3.0
LXC 3.0, unlike 2.1, doesn't support old configuration formats at all
and because our previous approach to handling old format was incomplete,
running `vagrant up` on a system with LXC 3.0 would fail, even if the
base box itself was made with modernized config.

This commit fixes this problem: is the box has a modern config, it's
going to be properly created and booted under LXC 3.0. It does so
without breaking the support for LXC < 2.1
