rust-dependencies: update `regex` to 1.3.9

Version `1.3.8` introduces support for empty alternations, which makes
previously disallowed patterns usable in `regex`.

From a user's perspective, this means that glob patterns like `*.py{,c}` will
no longer generate an "invalid" regex and will use the Rust path.

`1.3.9` is a bugfix release, might as well update to the latest one.
