dwarf_loader: Sync with LINUX_ELFNOTE_LTO_INFO macro from kernel

As long as I am using CONFIG_DEBUG_INFO_BTF=y with LLVM/Clang
I have noticed the below macros where defined unconsistently.

See here pahole latest Git...

[ pahole:dwarf_loader ]

  /* Match the define in linux:include/linux/elfnote.h */
  #define LINUX_ELFNOTE_BUILD_LTO                0x101

...and latest Linus v6.2-rc4+ Git:

[ linux:include/linux/elfnote-lto.h ]

  #define LINUX_ELFNOTE_LTO_INFO         0x101

Fix this by syncing the pahole macro with the one from linux-kernel.
