lxc: workaround to ignore deprecated

Recent patch did deprecate a standard POSIX function [1].

This is the build error:
| ../../../lxc-2.0.0/src/lxc/cgfs.c: In function 'cgroup_rmdir':
| ../../../lxc-2.0.0/src/lxc/cgfs.c:172:2: error: 'readdir_r' is deprecated [-Werror=deprecated-declarations]
|   while (!readdir_r(dir, &dirent, &direntp)) {
|   ^

|  extern int readdir_r (DIR *__restrict __dirp,
|             ^
