Since opencontainers/runtime-spec#164 (part of the v0.1.1 release [1]), Linux runtimes are required to supply these devices and mounts. Specifying them explicitly in the config should have no effect, and just makes the config longer than it needs to be.

Linux runtimes are not required to supply this [1,2]. We could supply it via ocitool, but I don't think its wise to try and define two standards (one in opencontainers/specs for what a runtime must supply, and another here with additional stuff), because I don't see a clear definition of something generally useful enough to go here but not in the spec. For example, hosts without CONFIG_POSIX_MQUEUE could be spec-compliant but unable to perform the mqueue mount I'm removing here.

@wking I don't mind merging this but will wait for runc to work with this. |

@mrunalp I don't think we should wait for runc to catchup to the spec. We are going to be out of sync no matter what. |

Most of these are covered by the requirements that landed in
opencontainers/runtime-spec#164, and I don't think the additional mqueue
mount is worth the space between the spec requirements and the
ocitools-generated configs. More details in the commit messages.
