Respun 2.6.18 tarballs

[John Ralls]

Bug 788191 reported that the tarballs originally shipped with the release worked only with Guile-2.0. This turned out to be due to an error in SWIG that's in the version on Fedora 25 which I used to create those tarballs. I've re-spun the tarballs and the reporter of the bug has tested that they are now correct.

The re-spun tarballs also include src/optional/python-bindings/__init__.py, reported as missing by another user.

The sha256 hashes for the re-spun tarballs are:
