Support jarjar sharding

- If the new option `jarjar_shards` is set, use this as the number
of shards and enable sharding.

- The plan is to use it on "big" jars such as framework-minus-apex, but
for now, we only use it in a "test" target,
`framework-minus-apex_jarjar-sharded`.

- Also add `framework-minus-apex_jarjar-sharded` to the various
hardcoded spacial cases.

Test: m framework-minus-apex framework-minus-apex_jarjar-sharded
  and make sure the javac output jars have the same entries.
