FindOpenMP: Use NO_DEFAULT_PATH where appropriate
OpenMP libraries must always be found in the implicit linking
directories of a compiler when using the OpenMP compile flag. If a suitable OpenMP library is also found in for example some CMAKE_PREFIX_PATH, this can lead to the module finding the incorrect library.
On the other hand, CMAKE_PREFIX_PATH can't ever be a location that we
need to consider since the OpenMP compile flag would not work if we
needed to.
