The previous selinux rules obtained via audit2allow didn't really
work with the case of apps connecting to the producer socket,
despite all the allow rules being correctly in place.
This was failing our CTS tests.
The reason for the failure (see denials pasted below) is due to
Multi Level Security (for multi-user), which was still preventing
apps form a different level to connect to the traced producer
socket and write to the shmem buffers they get passed back.
This CL tags the objects being accessed as mlstrusted.
CTS tests pass with this CL.

In this architecture, the system_server instructs the zygote to fork a
child-zygote to be the webview_zygote. The system_server tells this new
zygote to listen for fork requests on a random abstract unix socket of
its choosing.
A follow-up CL will remove the rules for starting webview_zygote via
init.

The intent of this flag is to disable tests during early device
