Android: Remove AndroidRunnable::{beforeStart,afterFinish}AdbCommands

We have nowadays two ways to pass data from run configurations to
tool that do not require intimate knowledge of the sender:

1. Using RunConfigurationAspects, accessible for all workers in a
   RunControl
2. Using RunWorker::recordData for an individual worker.

This removes the need to use specific fields in a runnable and
means that a tool plugin can be better separated from target plugins.

The approaches are not mutually exclusive, both use an string-ish
id, I chose here to use the same string when using both.

This patch here uses approach 2. for the GammaRay/Android combo.
It also fixes a (harmless) typo (s/POSTSTART/POSTFINISH).
