Stabilize timetz test across DST transitions. 

The timetz test cases I added in commit a9632830b were unintentionally
sensitive to whether or not DST is active in the PST8PDT time zone.
Thus, they'll start failing this coming weekend, as reported by
Bernhard M. Wiedemann in bug #16689.  Fortunately, DST-awareness is
not significant to the purpose of these test cases, so we can just
force them all to PDT (DST hours) to preserve stability of the
results.

Back-patch to v10, as the prior patch was.
