rootfs: fix golang version detection

Browse Source 
When the rootfs creation is used for PRs there is
not a match with a kata runtime version, in this
case lets clone the runtime repository and checkout
to the kata branch target. If is already cloned
this mean this was set by depens-on script or the user.

Fixes: #326
