bin: Add `bak` to temporarily rename files
This is helpful when troubleshooting things like module sourcing, etc.
For example, both my last commits needed to test that the nvim and tmux
configs worked both with and without local configs.
This could be done like so:
$ nvim # works
$ bak ~/.config/nvim/local.lua # shift aside
$ nvim # works
$ bak ~/.config/nvim/local.lua # revert
