QSettings: Fix handling of long long ints with CFPreferences back-end.

The CFNumberGetValue() function does not work as advertised: For some
(but not all) CFNumbers containing a long long value outside the range
of int, it returns true when asked to convert to an int, so the wrong
value is extracted from the CFNumber.
As a workaround, use CFNumberGetType() to find out whether the value
is actually an int.
