Create the kern.ccd sysctl sub-tree when built as a module. Even though 

the contents of the sub-tree are all structures, and thus not displayed
via sysctl(8), the info is potentially useful to programs.  (For example,
ccdconfig could use this to determine how many units are available.)

The sub-tree is already available when the module is included as built-in
module.
