Include core_lambda_stubs in core_oj.

core-oj already contains most of java.lang.invoke - there isn't
much point in complicating build rules for bundled targets by continuing
to rely on stubs. The stubs target continues to exist for compiling code
that contains Java 8 language features against the M sdk.

bug: 31675876
Test: make checkbuild
