Increment version code for S tzdata apex

The use of version code 300000000 has caused issues with devices
updating from R that have a copy of tzdata2 downloaded. The tzdata2
version "beats" the tzdata3 version code, but also cannot be used, so
devices end up with nothing mounted on /apex/com.android.tzdata/.
