Fix Build: folly with -Wmissing-braces

Summary:
[Folly] Fix Build: `folly` with `-Wmissing-braces`.

Construction of `std::array` with list-initialization for the contained C array requires double braces, per the standard.

Compilers accept it with single braces, but will reject it when `-Wmissing-braces` is passed.
