The `customize-controls` script depends on `wp-util`

[ocean90]

Since [30014] customize-controls is using wp.template() which is part of the wp-util script. But wp-util wasn't added as a dependency.
It's currently possible that the customizer loads without wp-util which leads to a JavaScript error:

customize-controls.js?ver=4.7-alpha-38627:501 Uncaught TypeError: wp.template is not a function

In 38628:

Customize: Add wp-util as a dependency for customize-controls.

Fixes #38107.
