Don't require ${PROJECT_NAME}_TRIBITS_DIR for includes of utils files (…

…trilinos/Trilinos#4796)

Changing MessageWrapper.cmake to require ${PROJECT_NAME}_TRIBITS_DIR broke the
deprecated TriBITS Dashboard Driver system (which was created by a contactor)
which is still being used for some Trilinos builds and CASL VERA builds.  That
system is not under any automated testing so it is easy to break and hard to
test if it is working.

I changed back to simple include(file) and set CMAKE_MODULE_PATH in
tribits_get_version_date.cmake.

This passes the existing TriBITS tests for tribits_get_version_date.cmake.

I did not manually test the deprecated TriBITS Dashboard Driver system but
there is an about 99.9% chance this will fix it and therefore fix
trilinos/Trilinos#4796.
