ANDROID: Protect Kunit & virtio modules

* This is to mark previously non marked modules as protected.
* This fixes the following error (while running `tools/bazel \
    run //common:kernel_aarch64_abi_update` to update the ABI manually):
  ```
  ERROR: protected exports list must be updated before updating ABI definition...
  ```
