netd: allow tcp_socket name_connect

The patch in 36a5d109e6953c63d2a865eab4c4d021aa52250b wasn't
sufficient to address DNS over TCP. We also need to allow
name_connect.

Fixes the following denial:

<5>[   82.120746] type=1400 audit(1830030.349:5): avc:  denied  { name_connect } for  pid=1457 comm="netd" dest=53 scontext=u:r:netd:s0 tcontext=u:object_r:port:s0 tclass=tcp_socket
