Run "ravenizer" on ravenwood jars

Ravenizer is a new tool to preprocess ravenwood tests.

It can optionally be applied to other java targets (for analyzing them,
etc).

The actual tool is being implemented internally, so in AOSP, we just
use a script that copies the jar file as a replacement.

Test: manual -- run `m RavenwoodBivalentTest` and make sure the ravenizer
    log message shows up.
Flag: EXEMPT host test change only
