EXIT_CONNECTOR and FORK_CONNECTOR must depend on NET

If you select some variable, you have to ensure that the dependencies of the select'ed variable are fulfilled.

This patch fixes the following link error:

 	---help---
 	  This is unified userspace <-> kernelspace connector working on top
 	  of the netlink socket protocol.
 
 	  Connector support can also be built as a module.  If so, the module
 	  will be called cn.ko.

 	---help---
 	  It adds a connector in kernel/exit.c:do_exit() function. When a exit
 	  occurs, netlink is used to transfer information about the process and
 	  its parent. This information can be used by a user space application.
 	  The exit connector can be enable/disable by sending a message to the
 	  connector with the corresponding group id.
 
 config FORK_CONNECTOR

 	  It adds a connector in kernel/fork.c:do_fork() function. When a fork
 	  occurs, netlink is used to transfer information about the parent and
 	  its child. This information can be used by a user space application.
 	  The fork connector can be enable/disable by sending a message to the
 	  connector with the corresponding group id.
