Devicelab

What is happening?

Some (if not all) of mac devicelab bots have permission denied when trying to create a directory in /opt/flutter.

For example, when installing Xcode, we download the Xcode app into /opt/flutter/xcode, however, if the xcode directory does not exist yet, it is created with mkdir. However, this fails due to file permissions.

mkdir /opt/flutter/xcode: permission denied

Either we need to update permission allowance or the xcode directory needs to be created manually when bots are set up.

Note: the xcode directory has the owner of swarming currently, which allows directories to be created inside of it

Steps to reproduce

ssh into a bot and do

mkdir /opt/flutter/xcode

Expected results

Directory gets created or is already there
