Environment variables are wrong when running code on language server

[tobil4sk]

More details here: HaxeFoundation/haxe/issues/10151

When running code using the --interp flag using the vshaxe language server, the Sys.environment() function gives the names of the system environment variables in lowercase.

class Main {
    static function main() {
        var env = Sys.environment();
        for (i => j in env)
            Sys.println(i + ": "+ j);
    }
}

This is also true when a haxe call results in running a haxelib on the server (eg compiling hxcpp). Any call to Sys.environment() in the neko file returns them incorrectly.

They are in the correct case if you do not use the language server.
