Move jarjar repackage action before combine action

With this change, the jarjar repackage actions are only on
the local classes of each module instead of the combined jar
that contains the static libs. The static libs don't need
jarjar repackage action on this module level because it has
been repackaged when building itself.

This change also removes the skip_jarjar_repackage property
since it's incompatible with this change. Actually skipping
jarjar repackage on a dep may result in incomplete repackage
on the module output.
