git-tagger.sh: merge the confirmation loop into the tagging loop
git-tagger.sh: merge the confirmation loop into the tagging loop

The old confirmation loop has a bug that it searches only
commit IDs of HEADs and tags returned by ls-remote.
This commit deletes the old confirmation loop and adds
fixed confirmations just before tagging or tag deleting.
