dwarves: Add -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 to build libbpf

We need that as the fix in upstream libbpf is in the
tools/lib/bpf/Makefile, that isn't used when building libbpf as part of
pahole, see:

  "Makefile: back-port _FILE_OFFSET_BITS=64 and _LARGEFILE64_SOURCE to Makefile"
  https://github.com/libbpf/libbpf/commit/4a50ceb0436f17a658b48fc03b8d72fb97522847

That refers to this in the kernel sources:

  71dd77fd4bf7 ("libbpf: use LFS (_FILE_OFFSET_BITS) instead of direct mmap2 syscall")
