store: lazily get file size on demand for the fncache case
We don't have the information in the first place, so we can avoid querying the
file system inconditionnaly for use case we don't needs it.
This change requires the StoreFile class to be passed a vfs to retrieve the
file_size if needed.
In the non-fncache case, we already have the information from file system
walking, so we keep it and use it.

store: only access is_volatile information through the file object
This make sure other code only access this information through the proper API,
and it prepare for store entries to be able to agregate multiple files.
