Fix ouput buffer limit test (#8803)

The tail size of c->reply is 16kb, but in the test only publish a
few chars each time, due to a change in #8699, the obuf limit
is now checked a new memory allocation is made, so this test
would have sometimes failed to trigger a soft limit disconnection
in time.

The solution is to write bigger payloads to the output buffer, but
still limit their rate (not more than 100k/s).
