Add a test that fails if a rule updates it output file but fails

https://groups.google.com/forum/#!msg/ninja-build/YQuGNrECI-4/ti-lAs9SPv8J
discusses a case where an rule updates its output file and then
fails.  The next run of ninja considers the ouptut file clean
and doesn't rebuild it.  Add a test for this case, which currently
fails.
