lavu/riscv: fallback to raw hwprobe() system call
Not all C run-times support this, and even then, it will be a while
before distributions provide recent enough versions thereof.
Since this is a trivial system call wrapper, we might just as well call
the corresponding kernel system call directly where the C run-time lacks
support but the kernel headers are new enough (as is the case on Debian
Unstable at the time of writing). In doing so, we need to add a few more
guards as the first suitable kernel (headers) release did not expose the
V, Zba and Zbb extensions.
