Make tests pass with -expt-extended-lambda on CUDA

[aprokop]

At the moment, tests fail due to using [=] instead of KOKKOS_LAMBDA for this configuration (for instance, kokkos/core/unit_test/TestCXX11.hpp:123)

Disable the tests for non-Cuda execution spaces if Cuda is enabled and experimental lambda is enabled.
