t6423: introduce Windows-specific handling for symlinking to /dev/null

The device `/dev/null` does not exist on Windows, it's called `NUL` there. Calling `ln -s /dev/null my-symlink` in a symlink-enabled MSYS2 Bash will therefore literally link to a file or directory called `null` that is supposed to be in the current drive's top-level `dev` directory. Which typically does not exist. The test, however, really wants the created symbolic link to point to the NUL device. Let's instead use the `mklink` utility on Windows to perform that job, and keep using `ln -s /dev/null <target>` on non-Windows platforms. While at it, add the missing `SYMLINKS` prereq because this test _still_ would not pass on Windows before support for symbolic links is upstreamed from Git for Windows.
