gnupg: fix find-version for beta checking

find-version always assumes that gnupg is beta if autogen.sh is run
out of git-repo. This doesn't work for users whom just take release
tarball and re-run autoconf in their local build dir.

This fixes runtime issue:

  $gpg --list-sigs
  gpg: NOTE: THIS IS A DEVELOPMENT VERSION!
  gpg: It is only intended for test purposes and should NOT be
  gpg: used in a production environment or with production keys!
