The Capabilities field on libcontainer is actually used as a mask.
Rename the field so that this is more clear.

Update fedora.rst

It looks like ``wmdocker`` does not have an update for Fedora 20:

```

```

I'm not sure if the owner awjb is intending to create an F20 update or
not, but either way -- these docs are incorrect as currently written.
