perf test: Use machine__new_host in dwarf unwind test
This is more straightforward than what we have now.
It also fixes a segfault within machine__exit, that's caused by 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
