[PATCH rcu 09/21] 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.
