Containerd pre-creates userns and netns before calling runc, which results in the current code not working when SELinux is enabled, resulting in the following error: > runc create failed: unable to start container process: error during container init: error mounting "mqueue" to rootfs at "/dev/mqueue": setxattr /path/to/rootfs/dev/mqueue: operation not permitted The solution is to become root in the user namespace right after we join it. Fixes opencontainers#4466.

[1.2] libct/nsenter: become root after joining userns
Since Go 1.19, the same functionality is there in os/exec package. As we require go 1.22 now, there's no need to have this. This basically reverts commit 9258eac ("libct/start: use execabs for newuidmap lookup").

Backport #4482
Because we have the overlay solution, we can drop runc-dmz binary solution since it has too many limitations.
The original post is here: #4450 (comment)
Because of there are many commits about runc-dmz binary solution, so doing git revert action is very hard, let's drop these code line by line.
