Do not set the `logtostderr` GLOG flag just to be on the safe side (#73360)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73360
Some (internal) PyTorch users use GLOG for their own logging purposes as well. Since the default setting is already to write to `stderr` anyways, let's be a good citizen and don't interfere with the logging settings of the main application.
