Adds additional 'enterprise' text underneath the 'startup' logo if the
ui is built with a CONSUL_BINARY_TYPE environment variable that doesn't
equal `oss`.
1. Prints the $version that you are passing through to the docker
container
2. Prints the CONSUL_VERSION that is used in the UI v2 footer
3. Additionally added a `mkdir -p` so so `make ui-docker` runs with a
clean exit if run in isolation
