I did give a try, using an amd64 mkimage image build from current tree (9.99.98/amd64):

Update the bootcode from /usr/mdec/mbr? [n] y
We haven't written the MBR back to disk yet. This is your last chance.
Should we write new partition table? [n] y

=====================================================================
Testing in qemu, I'm back to the original problem and stuck on primary bootstrap.
Either I'm missing one option to parse to the mkimage script to make the image bootable or there might be a trick to post proces the image afterward so that it can boot.
Image generated trough "build.sh live-image" work out the box:
bash-5.1# vndconfig vnd1 NetBSD-9.2-amd64-live.img
bash-5.1# fdisk -vv /dev/rvnd1
