elf: Keep only one '@' for undefined versioned symbols
The symbol string table in the .symtab section is optional and cosmetic.
Keep only one '@' for undefined versioned symbols, which are defined in
shared objects, in the symbol string table. Update "nm -D" to display
only one '@' for undefined versioned symbols.
