[Object/ELF] - Do not crash on invalid section index.
If object has wrong (large) string table index and
also incorrect large value for amount of sections in total,
then section index passes the check:
if (Index >= getNumSections())
return object_error::invalid_section_index;
But result pointer then is far after end of file data, what
result in a crash.
