Subject: Executor: Check validity of action outputs in compatible mode

This ensures that any entries that the standard remote execution
protocol accepts but are invalid in justbuild, i.e., upwards
symlinks, are rejected.

For this purpose, do not fail in the action response instances,
just perform the check there, as all required information is
available, and set a flag that the executor can check as needed.
