Fix bug 2022435.

After the user has initiated the download of the TTS language pack installer,
and that the installer has automatically started running, the installer
(in InstallerActivity) will broadcast an event
(TextToSpeech.Engine.ACTION_TTS_DATA_INSTALLED) to signal the completion
and success of the installation. The event is picked up by LangPackUninstaller
which triggers the deletion of the installer package to avoid wasting space
on the user's device.
