Brad King 4deaa25f46 ExternalProject: Fix UPDATE_DISCONNECTED with empty update steps ...

When `UPDATE_DISCONNECTED` is enabled the post-update steps
unconditionally depend on a `skip-update` step instead of `update`.
Make `skip-update` available whenever `UPDATE_DISCONNECTED` is enabled,
whether there is a real update step or not.

Closes: #16428
