package/busybox: disable CONFIG_FEATURE_IP_LINK_CAN if headers < 4.11

Browse Source 
Since the recent bump of Busybox to 1.37.0 in commit
ed84e971c3, the build fails on
configurations with old kernel headers. Indeed, the new
CONFIG_FEATURE_IP_LINK_CAN Busybox option uses IFLA_CAN_TERMINATION,
which was only introduced in Linux 4.11.

This commit addresses this issue by disabling
CONFIG_FEATURE_IP_LINK_CAN if the headers are not old enough.
