Use `command find` rather than plain `find`

Aliases are expanded in shell scripts, and one may have an alias
for the `find` command that conflicts with fzf. So make sure fzf
is using real find command rather than the alias.

Add vi-command keymap mappings

fzf does not currently define vi-command mode mappings. This is particularly annoying for <C-r>, which opens bash's old-fashioned recursive history search.

This patch adds vi-command mode mappings that simply drop back into vi-insert mode ("i") and then trigger the primary mapping.
