    PR26011, excessive memory allocation with fuzzed reloc sections

    Check sizes early, before users of slurp_relocs allocate buffers for
    the swapped in relocs.

            PR 26011
            * elf.c (_bfd_elf_get_reloc_upper_bound): Sanity check reloc
            section size against file size.
            (_bfd_elf_get_dynamic_reloc_upper_bound): Likewise.
