Error out early if system does not support pre-copy checkpointing
CRIU's pre-copy migration support relies on the soft dirty page tracking
in the Linux kernel:
https://www.kernel.org/doc/Documentation/vm/soft-dirty.txt
This functionality is not implemented for all architectures and it can
also be turned off in the kernel.
CRIU can check if the combination of architecture/kernel/CRIU supports
the soft dirty page tracking and exports this feature checking
functionality in go-criu.
This commit adds an early check if the user selects pre-copy
checkpointing to error out if the system does not support it.
