[PATCH 2/7] perf test: Use machine__new_host in mma thread lookup test

[Jiri Olsa]

This is more straightforward than what we have now.

It also fixes segfault within machine__exit, that's caused
but not creating kernel maps for machine.. We're calling
machine__destroy_kernel_maps in machine__exit since commit:

  ebe9729c8c31 perf machine: Fix to destroy kernel maps when machine exits
