restore join_string() symbols in library

To keep the library it backward compatible, instantiate versions
of join_string() for STL containers.

Old symbols (x86):

    0003a040 g    DF .text  00000083  Base        _ZN3I2n11join_stringERKSt4listISsSaISsEERKSs
    00039fb0 g    DF .text  00000084  Base        _ZN3I2n11join_stringERKSt6vectorISsSaISsEERKSs

New symbols:
