deps: upgrade to libuv 1.27.0

Notable changes:
- `statx()` is used to retrieve file birth times on
  supported platforms.
- Improved support of running under Windows safe mode.
- Add support for UDP connected sockets. Several functions
  can now return `UV_EBADF` instead of `UV_EINVAL`.
- SunOS support is improved.
