CLEANUP: config: Don't alter listener->maxaccept when nbproc is set to 1

This patch only removes a useless calculation on listener->maxaccept when nbproc
is set to 1. Indeed, the following formula has no effet in such case:

  listener->maxaccept = (listener->maxaccept + nbproc - 1) / nbproc;

This patch may be backported as far as 1.5.
