[PATCHv2 1/1] report_r_debug: handle `-z separate-code' and find more modules

Looking at some cores in eu-stack, I found that they were not being backtraced. This was because elfutils had not found some modules (e.g. libc-2.22.so) in report_r_debug. That is because it has a limit on the number of link map entries it will look at, to avoid loops in corrupted core files. Th

Further to: https://sourceware.org/pipermail/elfutils-devel/2023q2/006149.html This is a patch to increase the number of iterations looking for segments to load. This lets eu-stack backtrace cores that would otherwise fail. Florian Weimer and Mark Wielaard suggested both the explanation and
