Thomas Tauber-Marshall 01f436979c IMPALA-7990: make test_lifecycle_failures more permissive ...

test_lifecycle_failures runs a query with a debug action set to cause
fragment thread creation to fail 50% of the time and checks that the
query either succeeded or failed with an expected error.

Generally, the failure happens early enough that the query hasn't yet
reached FINISHED, but its also correct under Impala's query lifecycle
model for the query to reach FINISHED before the error is hit, in
which case it will be returned by a call to fetch().

Previously, the expected error in the test only handled the first
case. This patch modifies it to be more permissive in order to handle
both cases.

Testing:
- Ran test_lifecycle_failures in a loop 200 times without a failure.
  Previously it repro-ed for me ~10% of the time.
