Avoid double-installing Korman.

Don't install any copies of Korman that might be lurking inside the
Blender directory. This can easily result in interesting race conditions
where we can't predict what exactly will be installed. Worse, if the
korman installed to Blender is a Windows directory junction, then CPack
will fail with an inscrutable error.
