Allowlist frameworks/hardware/interfaces/stats/aidl

This fixes current breakage on aosp-master-bazel on bp2build-incremental. aosp/2401793 addes android.frameworks.stats-V2-ndk to libtestvendoratoms but android.frameworks.stats aidl_interface is not allowlisted yet.

However, `//frameworks/proto_logging/stats/stats_log_api_gen:libtestvendoratoms` is still not building because of another issue in genrule + proto.

```
ERROR: out/soong/workspace/frameworks/proto_logging/stats/stats_log_api_gen/BUILD.bazel:87:8: Executing genrule //frameworks/proto_logging/stats/stats_log_api_gen:test_vendor_atoms.cpp failed: (Segmentation fault): bash failed: error executing command (from target //frameworks/proto_logging/stats/stats_log_api_gen:test_vendor_atoms.cpp) /bin/bash -c ... (remaining 1 argument skipped)i
```

The fix to this is similar to aosp/2401794 and is fixed in aosp/2449265
