libdwfl: Don't trust e_shentsize in dwfl_segment_report_module
When calulating the possible section header table end us the actual size
of the section headers (sizeof (Elf32_Shdr) or sizeof (Elf64_Shdr)),
not the ELF header e_shentsize value, which can be corrupted. This
prevents a posssible overflow, but we check the shdrs_end is sane
later anyway.

Hmmm. At first I thought this was pretty useful to add to our own buildbot CI
setup. But it comes with a horribly proprietary license :{ "CodeQL can’t be
used for automated analysis, continuous integration or continuous delivery"
Sigh.
