fsck: handle sparse files efficiently, fix xfstests generic/285
If we encounter a 128KB block of zeros, try to skip to the next data section by calling File.SeekData(). This fixes xfstests generic/285, which creates a 17TB sparse file, and runs fsck afterwards. Without this optimization, fsck would take ages.
