ATDM: Set CTEST_BUILD_NAME by default to env<ATDM_BUILD_NAME>-exp for…

… 'dashboard' target

This only impacts the 'dashboard' target.  This gives a nicer build on CDash
when using the universal 'dashboard' target.  This should not impact the usage
of the other ctest -S drivers as part of the ATDM Trilinos configuration at
all.
