devicelab tests want ANDROID_SDK_ROOT but it is deprecated #117245
Description
If you run the devicelab tests it will complain that ANDROID_SDK_ROOT is not set. But if you set it, you'll no longer be able to compile the flutter engine because of the following error:
* What went wrong:
Could not determine the dependencies of task ':app:lintDebug'.
> Several environment variables and/or system properties contain different paths to the SDK.
Please correct and use only one way to inject the SDK location.
ANDROID_HOME: /Users/aaclarke/dev/engine/src/third_party/android_tools/sdk
ANDROID_SDK_ROOT: /Users/aaclarke/Library/Android/sdk
It is recommended to use ANDROID_HOME as other methods are deprecated
