CMake: Project Vars & Fix Memtest

PIConGPU project name: `PIConGPUapp` since this CMakeLists.txt
builds the final app.

Use the Project-specific name instead of the general CMake wide
prefix for variables such as the current source directory. Needed
for later includes in super-projects.

Fix the detection of cuda-memtest and mpiInfo.
