Nick Kralevich bafea958fb allow runas_app untrusted_app_all:unix_stream_socket connectto
system/sepolicy commit ffa2b61330
introduced the runas_app SELinux domain, which changed how we perform
debugging and profiling of Android applications. This broke Android
Studio's profiling tool.

Android Studio's profiling tool has the run-as spawned application
connect to an app created unix domain sockets in the
abstract namespace.

Note: this differs from system/sepolicy commit
3e5668f173, which allows connections in
the reverse direction (from app to runas_app). That change (b/123297648)
was made for a different part of Android Studio, Android Studio Instant
Run.
