For shadow builds where "make install" had not been run, the
tst_QLocale::emptyCtor test function would fail to find its helper
application because QFINDTESTDATA was not searching for it in the build
directory due to the test not instantiating QCoreApplication.
This commit fixes the test by instantiating a QCoreApplication using the
QTEST_MAIN macro, which also allows some special case code for Windows
CE to be removed.
