MINOR: startup: encapsulate sock_get_old_sockets in a function

Browse Source 
Let's encapsulate here the code, that calls sock_get_old_sockets() to obtain
listeners sockets from the previous process into a separate function. This
will make the code of main() more readable and we can move this new function
(if we might need so) in future.
