riscv64 syscall stub and seccomp filter generation.
These are sufficiently intertwined that they need to be done together.
riscv64 is our first primary-only architecture, so that required some
changes. The .bp changes are to support this --- we need to only show
the python scripts the architectures they'll actually be using, rather
than showing them everything and ignoring some of the results.
riscv64 is also the first architecture that post-dates the kernel's
64-bit time work, so there's a bit of extra fiddling needed to handle
the __NR3264_ indirection in the uapi headers.
