[PATCH] go: use a different goconfig package

[Justus Winter]

The notmuch-addrlookup utility uses a third party library to read the
notmuch configuration file. The previously used implementation at
"github.com/kless/goconfig" vanished, so this patch switches to the
implementation at "github.com/msbranco/goconfig". As the
implementations differ at the API level, the code is updated
accordingly.
