rbenv-rehash: use $OLDPWD to restore previous working directory

Browse Source 
$OLDPWD is a standard shell variable that contains the previous working
directory as set by the "cd" command. No need to save $PWD to some
custom variable.

(We could also have used "cd -" but it prints out $OLDPWD too.)
