Use export -U to deduplicate $PATH

In f7c73f7 we started to deduplicate `$PATH` using `typeset -U`, but that did not prevent duplicate `$PATH` entries when processes were launched that inherited the environment from an existing shell. Using `export -U` keeps the `$PATH` deduplicated even when tmux launches a new shell. Fix thoughtbot#443.
