replace github.com/golang/snappy with klauspost/compress/snappy

The github.com/golang/snappy repository was archived and is no longer
maintained. klauspost/compress provides a drop-in replacement, which
is actively maintained, and the klauspost/compress module is already
an existing (indirect) dependency.
