Add definitions in gtestsuite header to list available kernel
by AOCL BLIS version. Check these definitions in ukr test
programs to avoid missing symbol errors when testing with an
older version of BLIS.
Currently AOCL_41, AOCL_42, AOCL_50 and AOCL_DEV are supported,
with AOCL_DEV inferred from the version being later than the
value of AOCL_BLAS_LATEST_VERSION set in CMakeLists.txt. Thanks
to Eleni Vlachopoulou for the cmake functionality to automatically
detect the version from the library.
