XCB: Fix clipboard breaking when timer wraps after 50 days

All information below is from upstream commit
https://github.com/qt/qtbase/commit/036fe49580d7470eeaa4c168845bdf2483946f22

xcb_timestamp_t is a 32-bit unsigned value in miliseconds, so it
wraps after 49.7 days. When it happens, QXcbConnection::m_time stops
updating and copy & paste in an application would not work until the
application is restarted. This patch detects the timer wrap and
allows m_time to wrap too. The fix was verified in KDE desktop with
applications running for 51 days.
