store: initialize vfs field first to use it for initialization of others

This patch initializes "vfs" field in the constructor of each store
classes to use it for initialization of others.

In this patch, "self.vfs.base" is used to initialize "self.path",
because redo join of path components for "self.path" is redundant.
