[drtv] Add support for dr.dk/nyheder

It's the same video player, the only difference is that the video player
is loaded differently, and certain metadata (title and description) is
not available under dr.dk/mu, so make it by default get that from some
of the html meta tags.

Skip the dr.dk/tv test

dr.dk/tv videos are only available for between 7 and 90 days due to
Danish law, and in certain cases may be readded. Skip this test as it is
no longer available.
