mruby-fiber (fiber_to_s): retrieve position from terminated fibers; #6105

Browse Source 
Since `cxt->ci` points to the last active callinfo, `cxt->ci == cxt->cibase`
does not mean it does not have correct `proc` information, so we have
removed the `f->cxt->ci > f->cxt->cibase` check. Instead, just in case
`proc` does not have `irep` information, we try to confirm `proc` does not
point to `CFUNC` nor is not an alias.
