libmemunreachable: track kernel binder references

The kernel can hold references to binder objects that have no userspace
references.  Allow libmemunreachable to call into libbinder and
libhwbinder to get lists of kernel references.  Use undefined weak
symbols so that libmemunreachable will continue to work in processes
that do not have libbinder.

Test: memunreachable_binder_test
Bug: 28275695
