Re: readelf section reading
Fix commit 4de91c10cdd9, which cached the single section header read
to pick up file header extension fields. Also, testing e_shoff in
get_section_headers opened a hole for fuzzers where we'd end up with
segfaults due to non-zero e_shnum but NULL section_headers.
* readelf.c (get_section_headers): Don't test e_shoff here, leave
that to get_32bit_section_headers or get_64bit_section_headers.
(process_object): Throw away section header read to print file
header extension.
