Fix build failure for the openmp-target example when building in docker. (#197)

- Add cmake formatting rule for `rocprofiler-systems-custom-compilation`
- Resolve build failure observed with the `openmp-target` example when building in some environments
  - Observed in our docker images
  - Ensure `libomptarget-amdgpu-gfx*.bc` files are found
