dyndns-tests: Simulate job in wrapped execv
The function be_nsupdate_send fork a child for execution of the utility
nsupdate.
The child process builds nsupdate args in the function
be_nsupdate_args and then execute the utility.
Meanwhile the parent process register handlers for child and timeout
for canceling the long lasting child.
nsupdate_child_send -> child_handler_setup
You can see in following log file that the wrapped version of execv
function might be very fast and therefore parent can register handlers
after finishing child. This is a reason why there is a child timeout.

The patch simulate a work in wrapped function with small delay.
It should be enough time for the parent process to registering a child.
Based on patch from Jurica Stanojkovic <jurica.stanojkovic@rt-rk.com>
