tokio: fix cache line size for RISC-V #5994

  1. tokio: fix cache line size for RISC-V 

    Currently tokio uses cache line size data from Go, which is not
sufficient at least for T-Head C910 cores.

The RISC-V Profiles document defines a maximum 64 bytes cache line for
RVA22U64 (although the maximum is 128 bytes for RVA20U64), and the Linux
kernel currently assumes 64B cache line too.

Change the cache line size used to 64 bytes to match Linux and RVA22U64.
