It doesn't support other architectures. I found the build error on arm and decided to send the fix as it was creating noise on KernelCI. Hence I'm adding condition that memfd_secret should only be compiled on supported architectures. Also check in run_vmtests script if memfd_secret binary is present before executing it.
