Linked files shouldn't be touched before linked dirs creation

If file isn't placed in the top level directory, it's parent dir will not be created and `touch` will fail.

For example, basic rails project layout:
>** Invoke deploy:check:make_linked_dirs (first_time)
>** Invoke linked_files:touch (first_time)
>** Execute linked_files:touch
