netutil: in TestLimitListenerSaturation, allow some connections to fail to dial

When the listener saturates, the kernel will typically buffer the
remaining pending connections (so they will eventually succeed in
dialing). However, that behavior is not guaranteed, and it empirically
doesn't always hold: a failure was observed in
https://build.golang.org/log/5ac7312814bcff4841563be043f28aaefa9b3c90.

We do expect to be able to dial at least as many connections as the
listener will accept, and we expect every connection that is accepted
to be served to completion.
