runtime: support panic/print logging in android-L.
In android-L, logging is done through the logd daemon.
If logd daemon is available, send logging to logd.
Otherwise, fallback to the legacy mechanism (/dev/log files).
This change adds access/socket/connect calls to interact with the logd.
Fixes golang/go#9398.
