tst_QLocale: base europeanTimeZone test on 2013, actually used in test

The test that needs this bool is using 2013, so test that year for a
match. (Africa/Tunis toyed with DST in 1990, the year used before, but
thought better of it.) In the process, move the initialization to the
member-initialization of the class and make the member const.
