Description

This PR seems to address the expensive KokkosKernel unit tests described in https://github.com/trilinos/Trilinos/issues/2439#issuecomment-376554303.

I ran the KokkosKernel tests for this build and it gave:

Test project /home/rabartl/Trilinos.base/BUILD/WHITE/CHECKIN/gnu-debug-openmp
    Start 1: KokkosKernels_blas_openmp_MPI_1

8/8 Test #7: KokkosKernels_graph_serial_MPI_1 ....   Passed  416.39 sec

100% tests passed, 0 tests failed out of 8

Subproject Time Summary:
KokkosKernels    = 1452.77 sec*proc (8 tests)

Total Test time (real) = 416.41 sec

So if this PR is accepted, hopefully we will not see these timeouts going forward for debug-mode builds.
