Subject: Remove upstream git fanciness

Debian needs to be able to build libgpg-error while using git for
tracking the debian packaging itself.  Debian also wants to autoreconf
this stuff.  However, Debian does *not* need to conform exactly to
upstream's git configurations.

This avoids mistakes like accidentally identifying running code as a
beta.
