CMake: Set project file location in tealeaf mode

The tealeafreader creates a RawProjectPart for each cmake build target.
However, the location of the CMakeLists.txt is not set/added to
RawProjectPart::projectFile and RawProjectPart::buildSystemTarget.
Both properties are required by the AutoTest plugin to map
run configurations to test configurations.

Make tealeafreader use the same code as the servermodereader
to determine the location of the CMakeLists.txt.
