[ELF] - Set sh_info and sh_link for .rela.plt sections. This is https://bugs.llvm.org/show_bug.cgi?id=37538, Currently, LLD may set both sh_link and sh_info for .rela.plt section to zero when we have only .rela.iplt section part used. ELF spec (https://docs.oracle.com/cd/E19683-01/816-1386/chapter6-94076/index.html) says that for SHT_REL and SHT_RELA, sh_link references the associated symbol table and sh_info the "section to which the relocation applies." When we set the sh_link field, for the regular case we use the .dynsym index. For .rela.iplt sections, it is unclear what is the associated symbol table, because R_*_RELATIVE relocations do not use symbol names and we might have no .dynsym section at all so this patch uses .symtab section index.
