Android: enable tst_QLocale

Do not try to properly specify a path to an external syslocale app,
because the related test can't be executed on Android anyway.
This fixes a failure in initTestCase() and allows to unblock other
test-cases.
Also skip systemLocale() test, because Android platform plugin already
creates a custom QSystemLocale instance, so a hack with MySystemLocale
does not work.

As a drive-by: simplify the #ifery in initTestCase() and remove an
unused second parameter of QSKIP() in emptyCtor_data().

Fixes: QTBUG-87414
Pick-to: 6.3 6.2
