Switch back to Java android.util.Log
- Log is an important class, so this should always work even when
globalInitOnce fails().
- Also handle $RAVENWOOD_LOG_OUT at the very first.
Flag: EXEMPT host test change only
Fix: 377377826
Test: $ANDROID_BUILD_TOP/frameworks/base/ravenwood/scripts/run-ravenwood-tests.sh
Test: RAVENWOOD_LOG_OUT=$(tty) atest RavenwoodBivalentTest
# and make sure the log is printed on console.
