This can be used as a side channel to observe when an application
is launched.
Gate this restriction on the application's targetSdkVersion to
avoid breaking existing apps. Only apps targeting 34 and above will
see the new restriction.
Remove duplicate permissions from public/shell.te. Shell is
already appdomain, so these permissions are already granted to it.

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.

ro.secure and ro.debuggable system properties are not intended
