torture: Make kvm-recheck.sh skip kcsan.sum for build-only runs

Currently, kvm-recheck.sh attempts to create a kcsan.sum file even for build-only runs. This results in false-positive bash errors due to there being no console.log files in that case. This commit therefore makes kvm-recheck.sh skip creating the kcsan.sum file for build-only runs. Signed-off-by: Paul E. McKenney <[email protected]>
