[FIX] POSIX server builds broken by nightly patch

[freddyhayward]

The command line server build now fails because the #include-s were not updated in the simsys_posix.cc in the latest change to the file structure. I have updated them here which fixes the issue:
https://github.com/jamespetts/simutrans-extended/pull/237 . Hopefully you can merge this as soon as possible and force-update the server and downloads, or else it will not run for the next 20 hours.

Thank you for that - now incorporated and manual rebuild underway.

Thanks, the fix has worked and you can move this to the resolved section.
