media-tv/v4l-utils: Bump to 1.20.0, fix some automagics

The automagic libudev dependency has now been dealt with via a patch
and udev USE flag. Among other things, this library is needed for the
DVB utilities so a dvb USE flag has also been added with a
corresponding dependency on libv4l[dvb]. There may be more automagics
but I haven't checked yet.
