sstring: declare nested type with typename

per [temp.dep.type](https://eel.is/c++draft/temp.dep.type#5), `string_type::value_type` is considered a qualified name, and is a dependent type, so we have to prefix it with `typename` to make sure the compiler consider it as a type. Fixes scylladb#2327 Signed-off-by: Kefu Chai <[email protected]>
