vfs: simplify the handlers on WuiVfsOptions

Previously, the WuiVfsOptions contains two handlers: ListNodes to
retrieve list of files and OnClickNode for triggering changes when
user click a path or item in the list.

This changes simplify it into single handler: Open, which accept
path and boolean is_dir.
