[PATCH 0/1] MR2129: loader: In macOS preloader, fix an environment variable sometimes being lost.

[Brendan Shanks (＠bshanks)]

On Ventura (and likely also on Monterey), `dyld`/`libc` seems to store the `environ` pointer from when the preloader launches, ignores any change to `environ` done in the preloader, and then uses that original `environ` in the launched wine process.

The preloader has to move the start of the environment down by one, and this was causing the first variable to be lost on Monterey/Ventura. Instead of moving the entire environment, add a dummy variable at the beginning so nothing important is lost.
