Mark Ryan 8858c729c9 unix: update riscv_hwprobe constants 
Linux 6.5 enhanced the riscv_hwprobe syscall to detect four new
RISC-V extensions, V, Zba, Zbb and Zbs.  Update the hwprobe
constants in unix so these extensions can be detected by Go
programs.

Updates golang/go#61416

Mark Ryan 104d4017fa unix: add riscv_hwprobe for riscv64 
The riscv_hwprobe system call was introduced in Linux 6.4 and allows
the caller to determine a number of interesting pieces of information
about the underlying RISC-V CPUs, e.g., which extensions they support
and whether they allow fast unaligned memory accesses.  For more information
please see:

https://docs.kernel.org/riscv/hwprobe.html

We also update linux/mksysnum.go to ensure that the generated syscall constants
written to the zsysnum_linux_*.go files are always sorted by their syscall numbers
in ascending order.

Updates golang/go#61416
