Add alternative YouTube streams for Alhurra and Alhurra Iraq

Official website stream (already in the playlist) has issues
 (jittery, breaks out).

 No such issues from the official YouTube streams. So add those as
 alternatives.

 Didn't find info about alternative streams regarding naming, so
 just added "(Alternative)" to the name.
