ci-runner: only specify a numa node for performance stability (#685)

Previously we use numactl to specify both nodes and cpus for emu.
However, when other processes are using the same cpu, verilated emu
suffers from huge performance degradation. To avoid these scenarios,
we only specify the numa node to achieve a more stable performance.
