Use AF_INET sockets when checking netIds in setNetworkFor{Process,Resolv}(). DO NOT MERGE
AF_UNIX sockets don't need to be marked, so we don't give netd the permission to
operate on them (cf: netd.te). I.e., netd doesn't expect to receive them.
Make sure that the creation of the AF_INET socket doesn't trigger another
wasteful check with netd by calling the libc version directly.
