Subject: [PATCH 2/2] gnu: emacs-magit: Drop the libgit backend.

The libgit backend currently provides next to no features, but
demands extra maintenance overhead.  It is in fact not a usable
backend; thus let's not use it.

* gnu/packages/emacs-xyz.scm (emacs-magit)[arguments]
<emacs>: Remove this argument.
<exclude>: Exclude the magit-libgit.el and magit-libgit-pkg.el.

[inputs]: Remove emacs-libgit.
