Fix small bug in ZSTD_execSequence()

Fix small bug in ZSTD_execSequence()
...
`memmove(op, match, sequence.matchLength)` is not the desired behavior.
Overlap is allowed, and handled as if we did `*op++ = *match++`, which
is not how `memmove()` handles overlap.
Only triggered if both of the following conditions are met:
* The match spans extDict & currentPrefixSegment
* `oLitEnd <= oend_w < oLitEnd + length1 < oMatchEnd <= oend`.
These two conditions imply that the block is less than 15 bytes long.
This bug isn't triggered by the streaming API, because it allocates
enough space for the window size + the block size, so there cannot be
a match that is within 8 bytes of the end and overlaps with itself.
It cannot be triggered by the block decompression API because all of
the decompressed data is in the currentPrefixSegment.
