Brian Goff aab82bfc9c Ignore exist/not-exist errors on plugin remove ...

During a plugin remove, docker performs an `os.Rename` to move the
plugin data dir to a new location before removing to acheive an atomic
removal.

`os.Rename` can return either a `NotExist` error if the source path
doesn't exist, or an `Exist` error if the target path already exists.
Both these cases can happen when there is an error on the final
`os.Remove` call, which is common on older kernels (`device or resource
busy`).

When calling rename, we can safely ignore these error types and proceed
to try and remove the plugin.
