Stop java_sdk_library_import from depending on source modules

Previously, java_sdk_library_import added the dependencies on its child
components in the deps mutator after prebuilts without a matching
source module are renamed to the source module name. That meant that
the java_sdk_library_import has to use the source module name and ended
up depending on the source module unless it was preferred.

This change adds a new component deps mutator that runs before the
PrebuiltRenameMutator so that the java_sdk_library_import can add
dependencies onto the prebuilt modules. It also updates an affected
test.
