Continue test if the test for one board failed.

We run llvm validation test for several boards in a single script.
During the test, if something goes wrong and it calls logger.LogFatal(),
the whole test terminates because the LogFatal calls sys.exit() and
it will terminate the whole script. This CL fixes that by catching the
exception raised by sys.exit().

BUG=None
TEST=the SystemExit exception is handled.
