criu: Add support for time namespaces
The time namespace allows for per-namespace offsets to the system
monotonic and boot-time clocks.
C/R of time namespaces are very straightforward. On dump, criu enters a
target time namespace and dumps currents clocks values, then on restore,
criu creates a new namespace and restores clocks values.
