W. Trevor King 0aa6e4e5d3 libcontainer/specconv/spec_linux: Support empty 'type' for bind mounts ...

From the "Creating a bind mount" section of mount(2) [1]:

> If mountflags includes MS_BIND (available since Linux 2.4), then
> perform a bind mount...
>
> The filesystemtype and data arguments are ignored.

This commit adds support for configurations that leave the OPTIONAL
type [2] unset for bind mounts.  There's a related spec-example change
in flight with [3], although my personal preference would be a more
explicit spec for the whole mount structure [4].
