Stabilize jsonb_path_query test case.

Browse Source 
An operation like '12:34:56'::time_tz takes the UTC offset from
the prevailing time zone, which means that the results change
across DST transitions.  One of the test cases added in ed055d249
failed to consider this.

Per report from Bernhard Wiedemann.  Back-patch to v17, as the
test case was.
