Why not name the config file the same as Chromecast?

Whoa, this is backwards. Thanks for catching. It was not a 1:1 port from our
downstream, since that was handling this condition at a different code point.

This should be .eureka.conf for Chromecast (to stay with the existing file on
the device). I suspect that needs to remain permanently/until we decide to do a
one-time copy, so we don't lose the preferences.

"cast_shell.conf" was the name we settled on as a better "new name" for Android
build.
