Ensure property_set connection sockets are CLOEXEC.
When handling a property control message to start a service, the
connection socket was being left open. The child socket FD would then be
inherited by the service from init as "/null".
Bug: 34698883
Test: adb shell start webview_zygote32; adb shell ls -l /proc/<pid>/fd,
no "/null" FD open.
