Subject: [PATCH 1/3] notmuch: install the vim plugin

Install the vim plugin to $out/share/vim-plugins/notmuch and
$out/share/nvim/site/plugin/notmuch.vim. It is only static files and
doesn't add any dependency so it is enabled by default. Add `withVim`
argument to override this.

Subject: [PATCH 3/3] notmuch: vim ruby bindings and gems

We removed the ruby output so we will be able to reference the ruby files from
the vim plugin, which is in $out. If we try to reference $ruby from $out we get
a cyclic dependency.
