tivo: Fix Bonjour compatibility with Bolt

Bolt (Series6) seems to have a bug where it only reacts to
_tivo-videostream._tcp service types after a TiVo reboot, and ignores
_tivo-vidoes._tcp.  I have no idea what the difference is supposed to be
because it's undocumented, but either type works on both Roamio (Series5)
and Bolt, so hopefully it's safe for Series 3 and 4 also.
