PermissionDenied in docker run

The root cause is that current the base image of zeam is scratch which not compatible with io_uring. With hot fix adding `--security-opt seccomp=unconfined` could work but less secure. What is your thought for this issue? @gballet

No file or test is identified. Start by reproducing the PermissionDenied failure with the documented docker run command, then inspect the scratch base image and io_uring-related runtime configuration. Done means identifying a secure supported container configuration and documenting or testing the resulting docker run behavior.
