These commands are present in a recent version of the installation
image.  Perhaps the version you used is old enough that they are not
present?  Since Wayne also seems to have seen the same problem, I wonder
if perhaps it's an issue with an old image being hosted somewhere?
Where did you get the installation image?

I verified that the commands are present by running the following
commands from a system that has a recent version of Guix:

  $ guix system vm gnu/system/install.scm
  ...
  /gnu/store/zrcjqk520wlbq0m9rq8ss60sj24hjpjg-run-vm.sh
  $ /gnu/store/zrcjqk520wlbq0m9rq8ss60sj24hjpjg-run-vm.sh

The commands "passwd" and "ssh-keygen" were present at
/run/setuid-programs/passwd and
/run/current-system/profile/bin/ssh-keygen, respectively.

Similar to above, I can confirm that the programs "ssh" and "scp" are
present in a recent version of the installation image.

That sounds frustrating!  Maybe you can try first installing the "bare
bones" operating system (the example file for this is located at
/etc/configuration/bare-bones.scm in the installation image). After
you've booted into that initial bare bones operating system, you could
run "guix system reconfigure" using the actual operating system
configuration file you want.  That might help if the issue is lack of
storage space in the installation image.
