LibCore: Populate the read buffer of Core::Stream::BufferedHelper

Browse source 
Previously, we weren't ever populating the read buffer in read(), which
was making the BufferedHelper useless, how silly :^). This introduces
a buffer refill when we have run out of buffered samples, restoring
FlacLoader performance from the new low of 200% (directly before this
commit) to the old level of ~1400%.
