software/ors-amarisoft: Fix `render-templates -d` to remove all generated files

`render-templates -d` is used to remove all files that it previously
generated, so that it is easy to look around during development.

But, probably due to oversight, it was only *tdd files, that were
removed, with *fdd generated files still left in place.

-> Fix it.

The list of generated files, that is now additionally removed after this patch is:

        instance-fdd-enb-input-schema.json
