This fixes compilation issue in case memfd_create is a stub in libc.
Patch already merged in lxc master branch
(344b8ee293f4d3730a70a6ccaa03d7e4a516ae95).
Copy of the original commit log:
In case the internal memfd_create has to be used, make sure we don't
clash with the already existing memfd_create function from glibc.
This can happen if this glibc function is a stub. In this case, at
./configure time, the test for this function will return false, however
the declaration of that function is still available. This leads to
compilation errors.
