run-fio-tests: make test runs more resilient

Catch exceptions that occur during test setup/running/evaluation. This
makes it more likely that the entire test suite can run to completion
even if some tests fail in an unexpected fashion.

In particular I have seen failures in FioJobTest_t0014() when the test
is run on a bare metal machine. Without this patch these failures make
the entire script grind to a halt.
