[PATCH 2/5] Add SMB/CIFS mounts support

[Pavel Shilovsky <pshilovsky-eUNUBHrolfbYtjvyW6yDsg@public.gmane.org>]

From: Jeff Layton <jlayton-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>

The connectathon tests are also useful for testing SMB/CIFS filesystems
but when running without unix extensions, some tests are expected to fail.
Add a "CIFS mode" that skips tests that are known to fail when running on
CIFS filesystems without POSIX extensions.
