nvim: Use vim-system-copy

Use this so we do not pollute clipboard history. Also since neovim
depends on a provider which transparently uses shell commands to
communicate with the system clipboard, it seems this adds around 80ms
to start up.

074.721: sourcing /usr/share/nvim/runtime/autoload/provider/clipboard.vim

This plugin should allow us to depend on it only when required.
