Use securejoin.SecureJoin when forming userns paths

We need to read /etc/passwd and /etc/group in the container to
get an idea of how many UIDs and GIDs we need to allocate for a
user namespace when `--userns=auto` is specified. We were forming
paths for these using filepath.Join, which is not safe for paths
within a container, resulting in this CVE allowing crafted
symlinks in the container to access paths on the host instead.
