small fixes for delay

firstly, test_cipher_on_target() will try at least 4 connections before
incurring the sleep, for aggressive rate limiter on server side it may be
too much, so sleep before every connection

secondly, because running external commands like sleep incurs a fork
penalty, we first check if it is necessary
