config/unconfig.h: add this autoconf-generated file to the tree

<config/unconfig.h> is generated by autoconf (autoheader), but just
like the autoconf/helpers directory contains files for people who
don't have the proper tools, check this file in.

It should even be less annoying change-wise than the helpers...
