Fix corner case git log issue in generate_vcs_info.sh
This MR fixes a corner case with generating the VCS info header file that occurs if the user has
log.showsignature=true in their git config (like I do). In that case
git log -1 --pretty=format still includes the GPG signature output info, so we need to forcibly not show signatures when we actually want one-liner output.
