[committed] Fix Wformat warnings with make CC="gcc -m32"

[Tom de Vries <tdevries@suse.de>]

Hi,

We see this warning (and similar) with make CC="gcc -m32":
...
dwz.c: In function ‘calculate_section_distance’:
dwz.c:10517:47: warning: format ‘%lx’ expects argument of \
  type ‘long unsigned int’, but argument 4 has \
  type ‘GElf_Off {aka long long unsigned int}’ [-Wformat=]
      error (0, 0, "Section header table: [0x%lx, 0x%ld)", prev_offset,
...

Fix this by using %llx and casting the argument to unsigned long long.

Committed to trunk.

Thanks,
- Tom
