PR21990, Integer overflow in process_version_sections
This tidies some of the overflow checking when processing verneed
and verdef sections.
PR 21990
* readelf.c (process_version_sections <SHT_GNU_verneed>): Check
for invalid vn_next field before adding to idx. Use unsigned
long for index vars. Move index checks.
<SHT_GNU_verdef>: Likewise for vd_next.
