Only do DoVi remux when the client supports profiles without fallbacks

In 10.10 clients that can only play the fallback layer like the Samsung TVs will report `DOVIWithHDR10` as supported video range, but the server should not do remux in DoVi as the client can only play the fallback layer. This changes the server to only do DoVi remux when the client can play DoVi videos without a fallback layer.
