Android: Add QEXPECT_FAIL to flaky tst_android testFullScreenDimensions

This patch temporarily adds QEXPECT_FAIL to testFullScreenDimensions
test on Android 15.

Reason for this is that the testFullScreenDimensions from tst_Android
had been flaky on Android 15 and recently it had started to fail
continuously. QEXPECT_FAIL keeps CI status same between Android 14 and
15, before this test case is fixed.

Task-number: QTBUG-131338
