[vim] Expose buffer variable with the current fzf setup (#828)

Browse Source 
Exposing the `b:fzf` variable will be useful to get information about
which command is being executed on the current fzf window. With that,
now, it's possible to use the current command name on the statusline:

```viml
au User FzfStatusLine call <SID>fzf_statusline()

function! s:fzf_statusline()
  let fzf_cmd_name = get(b:fzf, 'name', 'FZF')
  let &l:statusline = '> '.fzf_cmd_name
endfunction
```
