hlsdemux: Always start playback at first fragment

Section 6.3.3 of the spec does not specify playback should be started three fragments from the end. It merely states that a client should not start playback closer than three fragments from the end on a live stream.

Until we have support for EXT-X-START, we should probably start at the first fragment unconditionally.
