hlsdemux: select correct position for live streams that don't remove fragments

Some live streams (eg youtube) don't remove fragments in order to allow
seeking back in time (live + vod).

When gst_m3u8_client_has_next_fragment is called, we are getting wrong fragment
because current_file points in first file of the fragments list resulting in
watching the stream from the beginning again.

This patch sets current_file to nth fragment for live streams, then on
gst_m3u8_client_has_next_fragment will keep up with the live stream.
