Jiong Wang 39b72ccdb2 tools: bpftool: add -DPACKAGE when including bfd.h
bfd.h is requiring including of config.h except when PACKAGE or
PACKAGE_VERSION are defined.

  /* PR 14072: Ensure that config.h is included first.  */
  #if !defined PACKAGE && !defined PACKAGE_VERSION
  #error config.h must be included before this header
  #endif

This check has been introduced since May-2012. It doesn't show up in bfd.h
on some Linux distribution, probably because distributions have remove it
when building the package.

However, sometimes the user might just build libfd from source code then
link bpftool against it. For this case, bfd.h will be original that we need
to define PACKAGE or PACKAGE_VERSION.
