Yuyang Huang cfdea5f4f3 Blocks untrusted apps to access /dev/socket/mdnsd from U
The untrusted apps should not directly access /dev/socket/mdnsd since
API level 34 (U). Only adbd and netd should remain to have access to
/dev/socket/mdnsd. For untrusted apps running with API level 33-, they
still have access to /dev/socket/mdnsd for backward compatibility.
