The code in Close() that removes the watches was not working,
because it first sets `w.closed = true` and then calls w.close(),
which starts with
```
if w.closed {
return errPollerClosed
}
```
Fix by setting w.closed only after calling w.remove() for all the
files being watched.
While at it, remove the duplicated `delete(w.watches, name)` code.

There is no need to wait for up to 200ms in order to close
the file descriptor once the chClose is received.
This commit might reduce the chances for occasional "The process
cannot access the file because it is being used by another process"
error on Windows, where an opened file can't be removed.

pkg/filenotify isn't used anymore and it causes problems with
hack/vendor.sh (nothing uses it, so hack/vendor.sh will remove the
vendored code).
