This allows Android to cleanly shutdown when running in a PID namespace in a way that does not rely on adbd running. This is useful to allow Android to be running in a container and its lifetime managed by an OCI-compliant tool. Bug: 65415372 Test: `kill -TERM 1` as root is correctly dropped. Test: `kill -TERM 1` from the init PID namespace causes init to cleanly shutdown. Change-Id: Ia66ebdb436221919081bc4723337c0c7f1e53b09
