  commit 451d1dc886b548d6e18c933adca326c1307023c9 upstream.

  Since, the new syntax of BTF-defined map has been introduced,
  the syntax for using maps under samples directory are mixed up.
  For example, some are already using the new syntax, and some are using
  existing syntax by calling them as 'legacy'.

  As stated at commit abd29c931459 ("libbpf: allow specifying map
  definitions using BTF"), the BTF-defined map has more compatablility
  with extending supported map definition features.

  The commit doesn't replace all of the map to new BTF-defined map,
  because some of the samples still use bpf_load instead of libbpf, which
  can't properly create BTF-defined map.

  This will only updates the samples which uses libbpf API for loading bpf
  program. (ex. bpf_prog_load_xattr)
