graphics/pgplot: Fix duplicate source file

[arichardson]

Summary

This will result in linker errors once https://reviews.freebsd.org/D26044
is commited since currently duplicates are silently filtered out.

You might want to bump portrevision as well, just to be sure.

Note, I haven't test built this, I trust that you've given it a spin in poudriere or similar.

[arichardson]

I'm not very familiar with the ports workflow and am not sure if I have commit access, so if someone could commit this for me that would reduce the chance of me messing up.

I tested building this locally using make clean all.

That should in general be enough. I can give it a spin in poudriere once I'm at my build box, but that will be some hours (and will be without your ranlib patches).

Ran it through my poudriere setup withot any issues.
