vendor: Update go-winio to v0.4.20

Updates go-winio to the latest v0.4.x version. The main important fix
here is to go-winio's backuptar package. This is needed to fix a bug in
sparse file handling in container layers, which was exposed by a recent
change in Windows.

go-winio v0.4.20: https://github.com/microsoft/go-winio/releases/tag/v0.4.20

// The logic for copying file contents is fairly complicated due to the need for handling sparse files,
// and the weird ways they are represented by BackupRead. A normal file will always either have a data stream
// with size and content, or no data stream at all (if empty). However, for a sparse file, the content can also
// be represented using a series of sparse block streams following the data stream. Additionally, the way sparse
// files are handled by BackupRead has changed in the OS recently. The specifics of the representation are described
// in the list at the bottom of this block comment.
//
// Sparse files can be represented in four different ways, based on the specifics of the file.
// - Size = 0:
// Previously: BackupRead yields no data stream and no sparse block streams.
// Recently: BackupRead yields a data stream with size = 0. There are no following sparse block streams.
// - Size > 0, no allocated ranges:
// BackupRead yields a data stream with size = 0. Following is a single sparse block stream with
// size = 0 and offset = <file size>.
// - Size > 0, one allocated range:
// BackupRead yields a data stream with size = <file size> containing the file contents. There are no
// sparse block streams. This is the case if you take a normal file with contents and simply set the
// sparse flag on it.
// - Size > 0, multiple allocated ranges:
// BackupRead yields a data stream with size = 0. Following are sparse block streams for each allocated
// range of the file containing the range contents. Finally there is a sparse block stream with
// size = 0 and offset = <file size>.
