debian/patches: Update Mir forward-port
- Allow clients that connect to a nested Mir server to safely bind to the display and get the actual device_name. Necessary for hardware-accelerated Wayland clients.
- Drop the patch that only worked around it and resulted in software-rendered clients.
- Fix the need to LD_PRELOAD the Mir Mesa platform, detection doesn't work in a libglvnd world anymore.
