[PATCH] dbghelp: Define NT_GNU_BUILD_ID regardless of whether __ELF__ is defined.

[Gerald Pfeifer]

[ Jacek, this materialized as a consequence of your changes 
  over the last 14 days, between Wine 5.4 and Wine 5.5. ]

In dlls/dbghelp/module.c we have unconditional code like the following:

    if (note[2] == NT_GNU_BUILD_ID)
    {

NT_GNU_BUILD_ID is #defined in image_private.h, which is #included by
module.c, alas that definition is conditional on __ELF__ *not* being
defined:

  #ifndef __ELF__
  :
  #ifndef NT_GNU_BUILD_ID
  #define NT_GNU_BUILD_ID 3
  #endif
  #endif

This causes problems on some (newer) versions of FreeBSD, where
apparently __ELF__ is defined while NT_GNU_BUILD_ID is not (at
least not without including sys/elf_common.h which we do not).

I do not have access to the version of FreeBSD 11.3 where that
issue was reported.  It did successfully pass on a different 
version of FreeBSD 11.3, though.
