Bazel is happier if Java/Java test roots are named 'java' and 'javatests', and
this will mean that once we create a BUILD file for
android/support/design/{widget,internal}/ we'll no longer need a custom package
specified in our build (which tends to cause build problems that manifest quite
weirdly). This commit doesn't attempt to refactor the build at all yet, and is
just a pure move.
