[PATCH] doc: improve config item labels in info output

[David Bremner <david@tethera.net>]

Commit 306b7028d added the nmconfig role / directive. Unfortunately
the default of using the directive name in texinfo output is pretty
ugly, so attempt to make it more human readable by passing `objname`
to add_object_type invocation.
