* cont.c (root_fiber_alloc): call `ConvertThreadToFiber()` here.

  `rb_fiber_t` for root_fiber is allocated before running Threads.
  Fiber objects wrapping this rb_fiber_t for root_fiber are created
  when root Fiber object is required explicitly (for example, Fiber
  switching and so on). We can put calling `ConvertThreadToFiber()`.
  In other words, we can pending `ConvertThreadToFiber()`
  until Fiber objects are created.
