Xamarin.Forms - Streaming from Encrypted Azure Media Services works on iOS and fails under Android

## 🐛 Bug Report

I have media (music) stored in an Azure Streaming Media Endpoint. The music is protected by token based authentication and as such during start-up I add the Auth Header like below:

`CrossMediaManager.Current.RequestHeaders.Add("Authorization", $"Bearer {token}");`

Then when I'm ready to play a song I do the following:

```
var url = song.DirectUrls.First(s => s.Contains("m3u")); //aapl
var mediaitem = await CrossMediaManager.Current.Extractor.CreateMediaItem(url);
mediaitem.MediaType = MediaType.Hls;

var item = await CrossMediaManager.Current.Play(mediaitem);
```

This works perfect in XF iOS and Fails in XF Android.

Here is the error message I see for XF Android:

```

It appears that it cannot access the media as seen by the ExoPlayer returning a 401 however the log does indicate: `[MediaHTTPConnection] response code = 200` so I'm not sure.

I've also tried switching the url to use the mpd format and set the MediaType to Dash but it still fails, although in this case ExoPlayer complains with
```

### Expected behavior

Should be able to stream on both XF iOS and XF Android

### Reproduction steps

### Configuration

**Version:** 0.8.8

**Platform:**
- [ ] :iphone: iOS
- [ ] :robot: Android
- [ ] :checkered_flag: WPF
- [ ] :earth_americas: UWP
- [ ] :apple: MacOS
- [ ] :tv: tvOS
- [x] :monkey: Xamarin.Forms

No repository files or tests are identified. Start by reproducing the Xamarin.Forms 0.8.8 sample with Azure Media Services token authentication, then compare the Android ExoPlayer requests with iOS and investigate the reported 401 response. Done means authenticated HLS or DASH media streams successfully on Android.
