Add logreqres:skip flag to new INFO obuf limit test (#12537)

The new test added in #12476 causes reply-schemas-validator to fail.
When doing `catch {r get key}`, the req-res output is:
```
3
get
3
key
12
__argv_end__
$100000
aaaaaaaaaaaaaaaaaaaa...4
info
5
stats
12
__argv_end__
=1670
txt:# Stats
...
```

And we can see the link after `$100000`, there is a 4 in the last,
it break the req-res-log-validator script since the format is wrong.

The reason i guess is after the client reconnection (after the output
buf limit), we will not add newlines, but append args directly.
Since obuf-limits.tcl is doing the same thing, and it had the logreqres:skip
flag, so this PR is following it.
