Pavel Emelyanov 05c0f8ed03 lister: Fix race between readdir and stat ...

Sometimes file::list_directory() returns entries without type set. In
thase case lister calls file_type() on the entry name to get it. In case
the call returns disengated type, the code assumes that some error
occurred and resolves into exception.

That's not correct. The file_type() method returns disengated type only
if the file being inspected is missing (i.e. on ENOENT errno). But this
can validly happen if a file is removed bettween readdir and stat. In
that case it's not "some error happened", but a enry should be just
skipped. In "some error happened", then file_type() would resolve into
exceptional future on its own.
