CMakeBuildSystem: Don't re-update code model on CMakeLists.txt saves

Currently if you edit a CMakeLists.txt and then press save, the code
model will be reindexed.

On projects like Qt Creator this operation is quite significant.

Note that the code model is updated after CMake has run on the project,
which is what I would expect.

Saving the CMakeLists.txt and not running CMake has no effect on the
project, and the code model shoudn't be reindexed.
