typing: add pseudo localstr.__init__() to help pytype

Apparently, pytype failed to parse localstr.__new__()? This fixes the
following errors:

  line 126, in __hash__: No attribute '_utf8' on localstr [attribute-error]
  line 188, in tolocal: Function localstr.__init__ was called with the wrong
  arguments [wrong-arg-types]
  Expected: (self, string: str, ...)
  Actually passed: (self, string: bytes, ...)
