cli: remove --compat for hawkmoth.util.doccompat based docstring proc…

…essing

The hawkmoth.util.doccompat module has been deprecated. Remove the
--compat option and the dependency on the module.

The alternative is to use the --process-docstring option. It does lack
the kernel-doc support, but it was simplistic to begin with.
