[llvm-objdump][ELF]Fix crash when reading strings from .dynstr (#125679)
This change introduces a check for the strtab offset to prevent
llvm-objdump from crashing when processing malformed ELF files.
It provide a minimal reproduce test for
https://github.com/llvm/llvm-project/issues/86612#issuecomment-2035694455.
Additionally, it modifies how llvm-objdump handles and outputs malformed
ELF files with invalid string offsets.(More info:

Fixes: #86612
