lxc: Backport patch that renames memfd_create() function

When Autotools makes configuration of LXC, the check of
the memfd_create() function fails because __stub_memfd_create and
__stub___memfd_create (The GNU C library defines this for functions
which it implements to always fail with ENOSYS) are defined in Glibc,
which leads to the fact that the macro HAVE_MEMFD_CREATE is not
defined and LXC provides defintion of the memfd_create() function as
static inline which in turn conflicts with a definition from
the <bits/mman-shared.h> file and causes an error:
| In file included from ../../../lxc-3.2.1/src/lxc/conf.c:79:
| <src_path>//lxc/syscall_wrappers.h:77:19: error: static declaration
