Do not use conf-man.py for non-manpage doc builds

Avoid importing conf-man.py for Sphinx invocations that do not build man
pages.  Since it only specifies man page build rules, it is not
necessary, and some of the targets do not have dependencies that would
ensure that it is present.

Fixes #2184.
