vppinfra: fix cpu time on riscv

Starting with Linux 6.6 [1], RDCYCLE is a privileged instruction on
RISC-V and can't be used directly from userland.Use RDTIME instead,
which while less accurate has the advantage of being synchronized
between CPU (and thus monotonic) and of constant frequency.

Type: fix
