elf_object_p load of dynamic symbols
This fixes an uninitialised memory access on a fuzzed file:
0 0xf22e9b in offset_from_vma /src/binutils-gdb/bfd/elf.c:1899:2
1 0xf1e90f in _bfd_elf_get_dynamic_symbols /src/binutils-gdb/bfd/elf.c:2099:13
2 0x10e6a54 in bfd_elf32_object_p /src/binutils-gdb/bfd/elfcode.h:851:9
Hopefully it will also stop any attempt to load dynamic symbols from
eu-strip debug files.
* elfcode.h (elf_object_p): Do not attempt to load dynamic
symbols for a file with no section headers until all the
program headers are swapped in. Do not fail on eu-strip debug
files.
