Konstantin Shegunov c6bee8e4b2 Fix integer overflows in QDeadlineTimer
If the deadline is far in the future, the conversions to nanoseconds
or internal arithmetic may overflow and give an invalid object, thus
the deadline may end up in the past. Added a test to the testlib
selftest for sleep.

[ChangeLog][QtCore][QDeadlineTimer] Fixed integer overflows
leading to immediate timeouts.

Task-number: QTBUG-69750
