vimPluginsUpdater: init

Browse source 
The nixpkgs documentation mentions how to update out of tree plugins but
one problem is that it requires a nixpkgs clone.
This makes it more convenient.
I've had the need to generate vim plugins and lua overlays for other
projects unrelated to nix and this will make updates easier (aka just
run `nix run nixpkgs#vimPluginsUpdater -- --proc=1` or with the legacy commands:
`nix-shell -p vimPluginsUpdater  --run vim-plugins-updater`.

I added an optional "nixpkgs" argument to command line parser, which is the path
towards a nixpkgs checkout. By default the current folder.
