Alexey Dobriyan 961a285132 build-id: require program headers to be right after ELF header
Neither ELF spec not ELF loader require program header to be placed right
after ELF header, but build-id code very much assumes such placement:

See

	find_get_page(vma->vm_file->f_mapping, 0);

line and checks against PAGE_SIZE.

Returns errors for now until someone rewrites build-id parser
to be more inline with load_elf_binary().
