net: bridge: add no_linklocal_learn bool option
Use the new boolopt API to add an option which disables learning from
link-local packets. The default is kept as before and learning is
enabled. This is a simple map from a boolopt bit to a bridge private
flag that is tested before learning.
v2: pass NULL for extack via sysfs
