Drop dot at the end of service type

The service type that found from NsdManager#discoverServices()
with old backend(mDnsResponder) has an extra dot at the end. And
the previous API accepted both formats, so we need to keep
backwards compatibility with both formats. Thus, drop that extra
dot when constructing the service type for the new backend.
