Alexander Egorenkov 38b520ab4c zdump/dfi_elf: Don't accept ELF input with zero-sized PT_LOAD segments ...

The DFI memory chunk manager cannot handle PT_LOAD segments of size 0.
This can lead to a NULL pointer access in mem_chunk_find() in case
zgetdump is given an invalid VMCORE ELF file as input which contains
only zero-sized ELF PT_LOAD segments. Instead of crashing, show an error
message and terminate gracefully.

The TELA test dump_with_zero_sized_segments.sh can reproduce this bug.
