Gate so_kernel_repo on running salt matching the shipped version

During soup the grid is mid-salt-upgrade. Only assign the UEK8 kernel
repo once the node's grains.saltversion matches salt.minion.version from
minion.defaults.yaml, so the kernel repo and the update it enables don't
activate until the node is fully on the target salt.
