  2. list: use Info(), fix race with delete 

    Since commit 5516294 we can (and should) use Info() to get access to
file stat. Do this.

While going over directory entries, a parallel runc delete can remove
an entry, and with the current code it results in a fatal error (which
was not observed in practice, but looks quite possible). To fix,
add a special case to continue on ErrNotExist.
