Set ro.traced.hypervisor sysprop when enabling traced_relay

Traced relay can only be used in virtualized environments, therefore set
the ro.traced.hypervisor sysprop to "true" in order to route VM-to-VM
communication through the host and make the unix socket connect call in
perfetto blocking in order to wait for the socket fd to be writable.
