Remove the dependence on x86 to run the memfd test. Verfied on 32-bit powerpc.

Now that most archs have __NR_memfd_create, this is:

Hmm. I am seeing failures on x86_64 on top of Linus's tree
(without this patch)

Could you please look into this?? It appears __NR_memfd_create isn't
defined on x86_64???

You need the headers installed in your system. By dropping the
arch-includes from the Makefile, we require 3.17 headers in
/usr/include.
