[OpenMP][OMPD] Fix compile error when OMPD is not supported

[mnadeem]

Summary

I am getting compilation errors after https://reviews.llvm.org/D100182

Error:

In file included from .../openmp/libompd/src/TargetValue.cpp:13:
 .../openmp/libompd/src/TargetValue.h:13:10: fatal error: 'omp-tools.h' file not found
 #include "omp-tools.h"

Looks like the file omp-tools.h is guarded like this:

if(${LIBOMP_OMPT_SUPPORT})
  configure_file(${LIBOMP_INC_DIR}/omp-tools.h.var omp-tools.h @ONLY)
endif()

Not familiar with the build system but here is an attempt to fix the issue.
