[CMake] Increasing test timeout during valgrind runs

[Leif Walsh]

Hi,

As should be expected, tests take a lot longer when run under
valgrind.  We'd like to keep a lower test timeout when running Test
actions, but increase that timeout when running MemCheck actions.  I
have a CTestCustom.cmake and a DartConfig.cmake that seem like likely
candidates.  Anyone know if this is possible and where it should go?
Or should I just add an option about letting tests run for a lot
longer, set it only in scripts that do a MemCheck round, and leave the
problem unsolved for developers running ExperimentalMemCheck?
