DO NOT MERGE Fake 29.0 sepolicy prebuilts

I took current AOSP policy as base, then removed sepolicy so that the
set of type and attributes was a subset of types and attributes in Q
sepolicy, with exception of those that have not yet been cleand up in
current AOSP:

mediaswcodec_server
netd_socket
mediaextractor_update_service
thermalserviced
thermalserviced_exec
