envutil.rb: timeout_error argument to invoke_ruby

* test/lib/envutil.rb (invoke_ruby): add `timeout_error` optional
  keyword argument, the exception class to be raised if the target
  process timed out.  if it is nil, no exception will be raised at
  timeout but the terminated output, error, and status will be
  returned.  defaulted to Timeout::Error.

* test/lib/envutil.rb (assert_separately): check outputs and
  status (including diagnostic reports) of timed-out process.
