Subject: [PATCH] schema: allow Device.fileMode set to null.

The `fileMode` is marked optional in the description (https://github.com/opencontainers/runtime-spec/blob/master/config-linux.md#devices)
In spec-go, fileMode can be set to null. (https://github.com/opencontainers/runtime-spec/blob/master/specs-go/config.go#L347).
However, in the schema, a null type is not allowed for fileMode.

This patch allows fileMode set to null, and consistent with other optional fields.
