openmp: Diagnose omp::directive/sequence on using-directive
With the using-directive parsing changes, we now emit only a warning
for [[omp::directive (...)]] on using-directive. While that is right
without -fopenmp/-fopenmp-simd, when OpenMP is enabled, that should
be an error as OpenMP (is going to) disallow such attributes there
as they do not appertain to a statement.

* name-lookup.c (finish_using_directive): Diagnose omp::directive
or omp::sequence attributes on using-directive.
* g++.dg/gomp/attrs-11.C: Adjust expected diagnostics.
