Subject: [PATCH] Fix division by zero in elfdeps (RhBug:2299414)

Conflict:NA
Reference:https://github.com/rpm-software-management/rpm/commit/02ffc5158d1ad270e0b5c7ce6dfe4414a6ec029f

Assume that the section does not hold a table if sh_entsize is 0 (as
specified in the elf(5) man page) and just skip it if that's the case.
