src: refactor cleanup logic to expose buildkitd.log

Previosuly, we only killed the buildkitd process and unmounted
if builderInfo was non null. This was wrong cause we could have setup
builkdkitd, but failed after that step. This would then rely on the last
ditch effort by the post action to cleanup. We now change the proc kill
and unmount to happen on any build error.
