Re: PR31692, objdump fails .debug_info size check

The fuzzers found a hole.  bfd_section_size_insane doesn't check
!SEC_HAS_CONTENTS sections against file size for obvious reasons,
which allows fuzzed debug sections to be stupidly large.  Real debug
sections of course always have contents.

PR 31692
* objdump.c (load_specific_debug_section): Don't allow sections
without contents.
