livepatch: Free klp_{object,func}_ext data after initialization
The klp_object_ext and klp_func_ext data, which are stored in the
__klp_objects and __klp_funcs sections, respectively, are not needed
after they are used to create the actual klp_object and klp_func
instances. This operation is implemented by the init function in
scripts/livepatch/init.c.
Prefix the two sections with ".init" so they are freed after the module
is initializated.
