Subject: [PATCH] orbital: Use `syscall::MAP_SHARED` for mapping

This seems to be required to work correctly since
https://gitlab.redox-os.org/redox-os/orbital/-/merge_requests/51.

Orbclient had a similar change:
https://gitlab.redox-os.org/redox-os/orbclient/-/commit/9097e71c9a61f0f654113881a485e16ce3854c62.
