Add helper gypi for predexing of prebuilt jars.

After https://codereview.chromium.org/12913009/ landed we need to change
the gyp targets that include prebuilt jars. Some of these live in
external repositories.

This adds a helper gypi for those targets so they are configured
correctly. This should also make it easier going forward to update such
targets.
