Make DST-transition test more general.

Widen its interval (to work in more TZs) and test spring as well as
autumn.  Anywhere that does have a DST transition probably has it
between August and December; and there's no benefit to using a narrow
window.

There's also no sense skipping the test if we don't know there's a DST
transition: the test should still work, it just won't be testing
anything (about DST transitions).

Combine date and time checks into date-time checks, so that, when one
of them fails, QCOMPARE lets us know how the other changed, too.
