The gen-header.sh script that generates libcamera.h takes all .h files in the include/libcamera/ directory, and manually adds the generated control_ids.h and version.h. This is fragile, as shown by the failure to add property_ids.h to the list in commitf870591a9b("libcamera: properties: Add location property"). To avoid future omissions, take all the .h.in files into account to generate libcamera.h. This also fixes the missing property_ids.h.
