IPv4: Extend 'fib_notify_on_flag_change' sysctl
Add the value '2' to 'fib_notify_on_flag_change' to allow sending
notifications only for failed route installation.
Separate value is added for such notifications because there are less of
them, so they do not impact performance and some users will find them more
important.
