[roll] Roll fuchsia [fdio] Use OwnedFd and BorrowedFd to respect IO safety

An upcoming version of Rust for debug builds will check that IO
primitives are respecting IO safety, and disallow I/O on file
descriptors that may be held privately elsewhere in the program.

To support this:

* `fdio::transfer_fd` now takes an `OwnedFd` since it modifies the file
  descriptor table for the descriptor..
* `fdio::create_fd` now returns an `OwnedFd`, since the caller has
  ownership over the returned descriptor.
* `fdio::clone_fd` now takes a `BorrowedFd`, since it does not need
  ownership over the descriptor.
* `fdio::clone_channel` now takes a `BorrowedFd`, since it does not need
  ownership over the descriptor.
