[roll] Roll fuchsia [fdio] hold root lock in `Export` Avoid the race condition where the namespace changes concurrently with export. Spotted by jamesr@google.com in https://fuchsia-review.googlesource.com/c/fuchsia/+/1152270. Add a test that caught the race condition under ASAN: ``` ERROR: AddressSanitizer: heap-use-after-free on address 0x47857e94c130 at pc 0x43ed1c9a11d0 bp 0x41d43b955d50 sp 0x41d43b955d48 READ of size 8

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance in one of the communication channels documented at get involved.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
