bpf: rename list_head -> graph_root in field info types

Browse source

Many of the structs recently added to track field info for linked-list
head are useful as-is for rbtree root. So let's do a mechanical renaming
of list_head-related types and fields:

include/linux/bpf.h:
  struct btf_field_list_head -> struct btf_field_graph_root
  list_head -> graph_root in struct btf_field union
kernel/bpf/btf.c:
  list_head -> graph_root in struct btf_field_info

This is a nonfunctional change, functionality to actually use these
fields for rbtree will be added in further patches.
