Move the CtsHostsideNetworkTestsAppNext to avoid automerger conflict

Move the CtsHostsideNetworkTestsAppNext to the top of file to to prevent
any future automerger merge conflict between aosp and downstream
branches. The CtsHostsideNetworkTestsAppNext target will not exist in
some downstream branches, but it should exist in aosp and some
downstream branches.
