Allows building OpenMP-V with ovni support, which is neccessary to run
the runtime tests of OpenMP-V in ovni.

The openmp derivation provides both libomp and libompv. To avoid
accidentally linking with the wrong library and to avoid the nosv
dependency on libomp, this patch separates each version in a different
derivation.
Also, it adapts the clang wrappers and stdenvs to provide an stdenv per
openmp library where each openmp will be used by default when the
compiler flag "-fopenmp" is used. This eases linking ompv with nixpkgs
libraries, such as blis, that expect openmp to be provided with stdenv.

Add a test to verify that "clang -fopenmp=libompv" links correctly with
nOS-V even though it is not placed in the buildInputs.

As the OpenMP-V implementation requires to be built with nOS-V, we can
split the OpenMP package in a different derivation to prevent rebuilds
of clang. Additionally, as OpenMP-V now can be build alongside the
vanilla OpenMP runtime, we simply build a single openmp derivation with
both runtimes. Only a single build of the clang compiler is now
required.

By default we build TAMPI with ovni support, as it will be disabled in
runtime unless explicitly enabled by the TAMPI_INSTRUMENT=ovni
environment variable.

In this test we ensure that the worksharing region is running inside a
nOS-V task, so we know that we are not using the vanilla OpenMP by
accident.
We also keep the previous test test/compilers/clang-openmp.nix as-is, so
we can check that the compiler injects the nosv library dependency in
the final binary on its own.

The binaries generated during the build process of clang are missing the
RPATH of the libstdc++.so library, which is provided by gcc libs.
Similarly, the clang binary itself also needs the rpath to the
libstdc++.so library path.

This is needed since nosv must appear as a 1rst level dependency on the
final executable. Clang will add the dependency as long as it knows
where to find nosv (and nodes is used).
