Fangrui Song 9dce25a9fa [llvm-objcopy] --add-symbol: fix crash if SHT_SYMTAB does not exist 
Exposed by D69041. If SHT_SYMTAB does not exist, ELFObjcopy.cpp:handleArgs will crash due
to a null pointer dereference.

  for (const NewSymbolInfo &SI : Config.ELF->SymbolsToAdd) {
    ...
    Obj.SymbolTable->addSymbol(

Fix this by creating .symtab and .strtab on demand in ELFBuilder<ELFT>::readSections,
if --add-symbol is specified.
