[PATCH] Fix off by one error in test

[Dale Hamel <dale.hamel@shopify.com>]

It doesn't affect the test outcome, but it is not the intended behaviour of
the test.

We listen once to find out what port to use, then should bind with SO_REUSEPORT
N-1 times, but we are doing it N times, so we have one extra listener.
