Enabling ompd tests that are disabled by this commit: https://github.com/llvm/llvm-project/commit/b5bf908fd7f87d2f0d74f62362a7e08366e926ff
This patch https://github.com/llvm/llvm-project/commit/1099498e3f35b2ad4b021ba3888b590259124e74 were failing differently in two different llvm-bots. Issues were failure at "cmake configuration" stage and test case failure at "openmp-offload-amdgpu-runtime"
Configuration issue: https://lab.llvm.org/buildbot/#/builders/84/builds/31109
Test case issues: https://lab.llvm.org/buildbot/#/builders/193/builds/21594 (couldn't reproduce locally)
This patch will make libompd build after libomptarget .
Configuration issue in debian machines seems to come from "find_package" of "libompd/test/CMakeLists.txt" which disables building DeviceRTL by messing up with "LLVM_DIR"
Also, I removed the code that looks for llvm-lit and filecheck as it is taken care by "OpenMPTesting.cmake"
