inet: Add getsockopt support for IP_ROUTER_ALERT and IPV6_ROUTER_ALERT
Currently getsockopt does not support IP_ROUTER_ALERT and
IPV6_ROUTER_ALERT, and we are unable to get the values of these two
socket options through getsockopt.
This patch adds getsockopt support for IP_ROUTER_ALERT and
IPV6_ROUTER_ALERT.
