network: fix memory leak in networkBuildDhcpDaemonCommandLine()

hostsfilestr was not being freed. This will be turned into g_autofree
in an upcoming patch converting a lot more of the same file to using
g_auto*, but I wanted to make a separate patch for this first so the
other patch is simpler to review (and to make backporting easier).

The leak was introduced in commit 97a0aa246799c97d0a9ca9ecd6b4fd932ae4756c
