devel/msgpack-cxx: Create even more links

msgpack has made an absolute mess of things.

For the cmake files, some ports want the new filename in the old
directory name, some want the new name in the new dir, some want the new
name in the old dir, and some want the old name in the new dir.

I'm over it. Let's make even more links (should fix opendht).
