IMPALA-6956: deflake and logging for query_expiration test

There was a recent flake where the number of in-flight queries
that were executing differed from the expected number.
The reason for the false negative is that one of the queries
expired before the check for in-flight queries: it took too long
to issue the queries.

This change modifies the timeout for the expired query to not expire
so quickly. Additional logging is added to the check for in-flight
queries so that we can distinguish the case of too few queries vs.
queries that have the wrong state.
