Since last time we checked, the kernel's security features on ARM have improved notably (see CONFIG_RANDOMIZE_BASE discussion). This patch therefore proposes to give the seccomp filter on both 32- and 64-bit ARM another try, since it provides significant security benefit to applications using it.

Due to operational constraints, rootfile changes have been omitted, and will be conducted, should this patch be approved.

Note to future self: Once this patch is approved, applications using seccomp (OpenSSH, Tor) need to be updated/shipped on ARM.
