Update. It turns out /usr/bin/ssh doesn't even exist when I run normally,
so that explains things somewhat. So I've added openssh to my app. It
appeared to build:

make[1]: Entering directory '/run/build/openssh/openbsd-compat'
make[1]: Nothing to be done for 'all'.
make[1]: Leaving directory '/run/build/openssh/openbsd-compat'

So there's the line:
/usr/bin/install -c -m 0755 -s ssh /app/bin/ssh

But /app/bin/ssh didn't end up in my final image:

bash-4.4$ cd /app/
bash-4.4$ find . | grep ssh
./etc/ssh_config
./etc/ssh_host_dsa_key
./etc/ssh_host_dsa_key.pub
./etc/ssh_host_ecdsa_key

./etc/ssh_host_ed25519_key.pub
./etc/ssh_host_rsa_key
./etc/ssh_host_rsa_key.pub
./etc/sshd_config
./libexec/ssh-keysign
./libexec/ssh-pkcs11-helper
./sbin/sshd

Anyone know why?
