Don't use ALL_PREBUILT

Bug: 6294985
With ALL_PREBUILT it just installs the data files to all devices.
We switch to a config.mk, which will be included by module definition of
VoiceDialer.apk and set up the necessary dependency.
TODO: modulize the config files and have VoiceDialer.apk depend on them.
