Subject: [PATCH] lxc-unprivileged: install /etc/sub{uid,gid}

Create default /etc/sub{uid,gid} files to use for unprivileged
containers.

Appearently these file are not generated/owned by any other OpenWRT
package or buildroot configuration setting.
If such a setting or package exists this commit should probably be
reverted an modified in an extra dependency for that setting/package.

In these default the range 100000-165535 is assigned to root
sub{uid,gid}.
