mobile: Remove jni_log

[fredyw]

The jni_log_fmt and jni_log functions have empty implementations and their uses are not very useful other than cluttering the code.

If you configure the JNI log, would it not write the output to standard logs such as when running the code in tests?

There's currently no way of configuring the JNI log other than manually updating the jni_log implementation. That's why in a8a60f6, the implementation was stubbed out when running on Android. For running the tests on Linux, we still have to do a manual std::{cout|cerr}, so in practice those JNI logs are not very worthwhile and are pretty spammy (I also haven't found them to be useful).

thanks for the cleanup!
