gnulib: build-aux/git-version-gen annotate

annotate build-aux/git-version-gen @ 14093:bae3b310c970

git-version-gen: include command name in one more diagnostic * build-aux/git-version-gen: When the required .tarball-version file was missing or unreadable, you might see the diagnostic from "cat", but no trace of the name of the invoking script. Now, you still see the diagnostic from cat, but also get one from "git-version-gen: ". Inspired by a patch from Bruce Korb.
