fzf keybinding doesn't work

[timurb]

With plain fzf integration I can hit Ctrl-R and search history with fzf.
With fzf-obc the standard "reverse-i-search" is used.

This probably can be fixed by simply sourcing /usr/local/opt/fzf/shell/key-bindings.bash as it was previously done in ~/.fzf.bash

Indeed, because i never planed to replace the other fzf default capabilities who works great.
I just forgot that fzf install script doesn't had keybindings and do its updaterc by default and should add this in install instructions if a user install fzf for the first time.
