vim:keys: Nvim does not replace has('clipboard')

Neovim does not make `has('clipboard')` obsolete. It only simplifies
clipboard support but `has('clipboard')` will still return `0` if no
supported clipboard program is installed.

See `:help clipboard`

    Nvim has no direct connection to the system clipboard. Instead it
    depends on a |provider| which transparently uses shell commands to
    communicate with the system clipboard or any other clipboard
    "backend".

and `:help clipboard-tool`

    The presence of a working clipboard tool implicitly enables the '+'
    and '*' registers. Nvim looks for these clipboard tools, in order of
    priority:

      - |g:clipboard|
      - pbcopy, pbpaste (macOS)
      - wl-copy, wl-paste (if $WAYLAND_DISPLAY is set)
      - xclip (if $DISPLAY is set)
      - xsel (if $DISPLAY is set)
      - lemonade (for SSH) https://github.com/pocke/lemonade
      - doitclient (for SSH)
        http://www.chiark.greenend.org.uk/~sgtatham/doit/
      - win32yank (Windows)
      - termux (via termux-clipboard-set, termux-clipboard-set)
      - tmux (if $TMUX is set)
