Change gopkg.in/fsnotify.v1 to github.com/fsnotify/fsnotify

`github.com/go-fsnotify/fsnotify` recently moved to
`github.com/fsnotify/fsnotify`. So far Github has automatically
redirected anyone coming from `gopkg.in/fsnotify.v1` to
`github.com/fsnotify/fsnotify`. This worked until today someone created
a new github repo under the old `github.com/go-fsnotify/fsnotify`.

Instead of referencing this dependency via `gopkg.in/fsnotify.v1`, this
patch references it directly via `github.com/fsnotify/fsnotify`.
