cgroup.c: fix a compiler warning

Got this trying to compile vzctl:

	  CC     cgroup.lo
	cgroup.c: In function 'container_apply_config':
	cgroup.c:109:4: warning: passing argument 3 of 'cgroup_get_value_uint64'
	from incompatible pointer type [enabled by default]
	/usr/include/libcgroup/groups.h:432:5: note: expected 'u_int64_t *' but
	argument is of type 'long unsigned int *'

Apparently we need to use u_int64_t here, like in other similar places.

Introduced in commit a6e1fda.
