Add early exit for exopackage test
Add early exit for exopackage test

Summary:
When the exopackage test can't communicate with a device, it does a
bunch of work before actually failing. This just adds an early call to
adb that will fail if it can't communicate with a device (because there
isn't one or because there are multiple and ANDROID_SERIAL is unset
or whatever)

Test Plan: manual testing
