f86d868274 sandbox: wrap error with its own text message
PathError has a pretty good text message, many of them are wrapped with its own text message. This change adds a function to do just that to improve readability.

33940265a6 sandbox: do not ensure symlink target
This masks EEXIST on target and might clobber filesystems and lead to other confusing behaviour. Create its parent instead.

e8809125d4 sandbox: verify outcome via mountinfo
This contains much more information than /proc/mounts and allows for more fields to be checked. This also removes the dependency on the test package.

9ddf5794dd sandbox/vfs: implement proc_pid_mountinfo(5) parser
Test cases are mostly taken from util-linux. This implementation is more correct and slightly faster than the one found in github:kubernetes/utils.
