RISC-V SECCOMP support for v5.4-rc5

This pull request contains a single change: the addition of SECCOMP
support for RISC-V for v5.4-rc5.  Normally, I'd consider this too
large for this point in the -rc releases.  However, we've heard that
v5.4 is likely to be a long-term support release, and adding it in now
should help the distribution and security folks.  The changes look
relatively bounded, and the only reason we've been sitting on it until
now is because we've been waiting for a trivial ack from the
tools/testing maintainer.  That hasn't come.  Since the change to that
subsystem is quite minor, we think it should be OK with her, so,
sending it now.

If you have a different opinion about whether this patch should go in
now, we're fine with requeuing it for v5.5-rc1.
