cleanup: remove redundant model source files in CMakeLists.txt

The divetripmodel.cpp, models.cpp and tankinfomodel.cpp source
files as well as the corresponding headers were listed as "general"
and as "desktop" models, i.e. twice. Remove the redundant entries in
the desktop list. This should have no consequence whatsoever.
