elf: Earlier missing dynamic segment check in _dl_map_object_from_fd
Separated debuginfo files have PT_DYNAMIC with p_filesz == 0. We need to check for that before the _dl_map_segments call because that could attempt to write to mappings that extend beyond the end of the file, resulting in SIGBUS. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
