livepatch: Add stack_order sysfs attribute
Add "stack_order" sysfs attribute which holds the order in which a live
patch module was loaded into the system. A user can then determine an
active live patched version of a function.
cat /sys/kernel/livepatch/livepatch_1/stack_order -> 1
means that livepatch_1 is the first live patch applied
cat /sys/kernel/livepatch/livepatch_module/stack_order -> N
means that livepatch_module is the Nth live patch applied
