checkCriuVersion: switch to version using int
checkCriuVersion: switch to version using int

The checkCriuVersion function used a string to specify the minimum
version required. This is more comfortable for an external interface
but for an internal function this added unnecessary complexity. This
changes to version string like '1.5.2' to an integer like 10502. This is
already the format used internally in the function.
