ridmap indicates that the id mapping should be applied recursively (only
really relevant for rbind mount entries), and idmap indicates that it
should not be applied recursively (the default). If no mappings are
specified for the mount, we use the userns configuration of the
container. This matches the behaviour in the currently-unreleased
runtime-spec.
This includes a minor change to the state.json serialisation format, but
because there has been no released version of runc with commit
fbf183c6f8 ("Add uid and gid mappings to mounts"), we can safely make
this change without affecting running containers. Doing it this way
makes it much easier to handle m.IsIDMapped() and indicating that a
mapping has been specified.
