  cgfsng: add cgfsng_monitor_destroy()

Since we switched to the new cgroup scoping scheme that places the
container payload into lxc.payload/<container-name> and
lxc.monitor/<container-name> deletion becomes slightly more complicated.
The monitor will be able to rm_rf(lxc.payload/<container-name>) but will
not be able to rm_rf(lxc.monitor/<container-name>) since it will be
located in that cgroup and it will thus be populated.
My current solution to this is to create a lxc.pivot cgroup that only
exists so that the monitor process on container stop can pivot into it,
call rm_rf(lxc.monitor/<container-name>) and can then exit. This group
has not function whatsoever apart from this and can thus be shared by
all monitor processes.

  cgfsng: ensure no-reuse in cgfsng_monitor_create()

The same way we need to ensure that no existing cgroups are reused for
the payload in cgfsng_payload_create() we need to ensure that no
existing cgroups are reused for the monitor. Technially this is less of
an issue since there currently is no logic for the monitor to apply
limits to its cgroup but it is still the proper way to do it.
