Andreas Heinisch 17154ceafe tdf#92620 - Adjust error message about exceeding legacy module size
Adjusted the error message about exceeding legacy module size and
removed the code for saving image version 11. Modules using image
version 11 still can be loaded. Saving modules always result in
an image version higher than image version 11 depending on the
size of the module.

In addition, some minor performance issues (construction of the error
message and the correct list of modules) were fixed.
