Allow mediaserver to connect to tee service.

Resolves denials such as:

avc:  denied  { connectto } for  pid=7028 comm="wfd_looper" path=006D636461656D6F6E scontext=u:r:mediaserver:s0 tcontext=u:r:tee:s0 tclass=unix_stream_socket

This is a socket in the abstract namespace so no socket file is involved.
