Fix native library loading failure caused by incorrect buffer comparison (#317) (#318)

Compare only the bytes actually read from each stream instead of the
entire 8192-byte buffer in contentsEquals(). When the final chunk is
smaller than the buffer, stale bytes from the previous iteration could
cause a false mismatch, preventing the native library from loading.

Uses a byte-by-byte loop instead of Arrays.equals() to maintain JDK 8
compatibility.

Fixes #317
