Fix generation of IOMDHAL.yml

This one is a special case where the superproject name mismatches the
corresponding Env (and thus Components) file.

Our own CI script also didn't previously support the *removal* of an
autogenerated YAML file. This should be a rare occurrence, but it's best
to automate this also. Also support force-pushing to the submodule; this
will be required in most cases where the pipeline was triggered by a
force-push to *this* project.
