openmp: For C++ ensure nothing directive has no operands
When working on error directive, I've noticed that while C FE diagnosed
clauses on nothing directive which doesn't allow any, the C++ FE silently
accepted it.

* parser.c (cp_parser_omp_nothing): Use cp_parser_require_pragma_eol
instead of cp_parser_skip_to_pragma_eol.
* c-c++-common/gomp/nothing-2.c: New test.
(cherry picked from commit 4e6a5fa403782590088b2796261b023963f912af)
