Mike Rapoport ef1b144d23 tools/virtio/ringtest: fix run-on-all.sh to work without /dev/cpu

/dev/cpu is only available on x86 with certain modules (e.g. msr) enabled.
Using lscpu to get processors count is more portable.

Partial implementation of various ring layouts, useful to tune virtio design.
Uses shared memory heavily.

Typical use:

# sh run-on-all.sh perf stat -r 10 --log-fd 1 -- ./ring
