Ensure suffix always applied to source dist.

This fixes the problem where the base name ends with something that already looks like a suffix.

In particular, the name chiabip158-0.13.dev3 was not getting the .tar.gz suffix.

This workaround works for me in my SConstruct file.

# workaround of an enscons bug
# in some cases, such as "chiabip158-0.13.dev3" if the base name
# of the source distribution already looked like it had a suffix,
# the TarBuilder would not add the ".tar.gz" suffix. This
# hack fixes it. It needs to go after the enscons.generate is added
# to tools, but before the SDist is created

enscons.pytar.TarBuilder.ensure_suffix = True

Beautiful.
