Add trace for GetHostByName and GetHostByAddr

Like GetAddrInfo and ResNSend, GetHostByName and GetHostByAddr should
print the caller uid so that we can know which app is flooding DNS
queries.

Bug: 246102271
Test: run ResolverTest#GetHostByAddr_ReverseDns64Query,
      ResolverTest#GetHostByName and check resolver logs.
