Description

For rootless container, if the runc binary has a 111 permission, runc can't work for this case.
The error message:
error msg="runc run failed: unable to create new parent process: unable to create safe /proc/self/exe clone for runc init: opening current binary: open /proc/self/exe: permission denied"

Research direction

Start by reproducing the rootless-container case with the runc binary set to 111 permissions and inspect the reported failure around /proc/self/exe. Done means rootless runc can run with that permission setting without the permission-denied error.
