Subject: [PATCH] Fix missing ROS2MedkitCompat.cmake in sensor_diagnostics
 Dockerfile

Preserve the shared CMake module from the ros2_medkit clone before
deleting it. Without this, colcon build fails because
ros2_medkit_serialization (and other packages) cannot resolve
their ../../cmake/ROS2MedkitCompat.cmake include path.

Fixes selfpatch/selfpatch_demos#28
