Add trap to cri-integration test script

The cri-integration.sh script sets errexit option. This does not
work properly on Bash in Windows, espectially when the script is
piped to something else ( tee in this case ). In this particular
case, the problem arises from the fact that if the script exits
prematurely, it will not get a chance to call test_teardown and
thus clean the remaining containerd process, thus the whole
command will hang indefinetly.

Adding a simple trap on EXIT to call test_teardown will easily
fix this.
