When building a change for operations/software/gerrit/plugins/events-wikimedia the job wipe the `log` dir but fails due to a missing permission:
```
+ exec docker run --entrypoint=/usr/bin/find --user=nobody --volume /srv/jenkins/workspace/gerrit-events-wikimedia-bazel-docker:/workspace --security-opt seccomp=unconfined --init --rm --label jenkins.job=gerrit-events-wikimedia-bazel-docker --label jenkins.build=26 --env-file /dev/fd/63 docker-registry.wikimedia.org/buster:latest /workspace/log -mindepth 1 -delete
++ /usr/bin/env
++ egrep -v '^(HOME|SHELL|PATH|LOGNAME|MAIL)='

The file `bazel-out/k8-fastbuild/bin/external/bazel_tools/tools/jdk/platformclasspath_classes/DumpPlatformClassPath.class` has permissions `-r-xr-xr-x` and the parent directory has `dr-xr-xr-x`. The `find` command is thus unable to delete the file since the directory lack the write permission.
