```
zstandard: fix incorrect RLE decompression into ring buffer

This reverts a change introduced in #17400 causing a bug when
decompressing an RLE block into a ring buffer.

RLE blocks contain only a single byte of data to copy into the output,
so attempting to copy a slice causes buffer overruns and incorrect
decompression.

```
