reland: untrusted_app_29: add new targetSdk domain
Enforce new requirements on app with targetSdkVersion=30 including:
- No RTM_GETLINK on netlink route sockets.
Remove some of the repetitive descriptions in each untrusted_app_N.te
file, and instead refer to the description in
public/untrusted_app.te.
