[PATCH bpf-next v2 03/11] libbpf: rename btf_{hash,equal}_int to btf_{hash,equal}_int_tag

[Yonghong Song <yhs@xxxxxx>]

This patch renames functions btf_{hash,equal}_int() to
btf_{hash,equal}_int_tag() so they can be reused for
BTF_KIND_TAG support. There is no functionality change for
this patch.
