LibAudio: Skip FLAC samples even if already close to seek target

Previously, the FLAC loader would not skip samples to reach its seek
target if it saw that the current sample in the loader is closer to the
target than the seek point it finds. This prevents seeking forward when
there are no seek points past the current position.
