Subject: [PATCH] selftests: memfd_secret: don't build memfd_secret test on unsupported arches
[1] mentions that memfd_secret is only supported on arm64, riscv, x86
and x86_64 for now. 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.
