* Revert "conf: remove extra MS_BIND with sysfs:mixed"
This should let privileged Ubuntu 14.04 containers boot
again.
* conf: use SYSERROR on lxc_write_to_file errors
Slightly more useful error output in a specific error
case.

The default cgroup pattern was switched from lxc/%n to
lxc.payload/%n, so add a ./configure option to revert this
change as PVE expects containers in lxc/%n.
