[4/4] tests/TestSuite_vm_pw_mgmt_policy: change core_mask

  Change the vm_power_manager core mask and guest_vm_power_manager
core mask.

Now with dpdk 20.11 the cores used for guest_cli
should be enabled in vm_power_manager core mask.
Otherwise vm_power_manager will not grant the access to
fetch the information for those cores missing in the coremask.

Relevant DPDK patch

Some server may not have so many cores, prefer to get_cores_mask("all") if need many cores.

AFAIK, get_cores_mask("all") will return all cores except the core0. I actually need the core0 too.
Is there any API that I can use which returns core 0 too, if not I might need to have this explicit core mask.

Set bypass_core0=False, then DTS will utilize core 0.
