Accept --target_label, --injecting_rule_kind in Turbine.

The values (if present) are written into the manifest with this format:

Target-Label: <label>
Injecting-Rule-Kind: <kind>

In the future, JavaBuilder will make sure of this instead of command
line arguments to find owners for jars for its add_dep commands.
