VMware Fusion can't find IP address on Big Sur

[lloeki]

I'm not sure why, but instead of using vmrun, the vmwarefusion driver attempts to find the guest IP through roundabout ways by looking into DHCP lease files.

With the advent of Big Sur, this doesn't work anymore as vmnet1/vmnet8 have disappeared in favour of a native bridge100 interface.

Comparatively, vmrun getGuestIPAddress just works:

~> vmrun list
Total running VMs: 1
/Users/lloeki/.docker/machine/machines/fusion/fusion.vmx
~> vmrun checkToolsState /Users/lloeki/.docker/machine/machines/fusion/fusion.vmx
running
~> vmrun getGuestIPAddress /Users/lloeki/.docker/machine/machines/fusion/fusion.vmx
172.16.159.2

I suppose it might just be a case of writing a getIPfromVmrun() or something.
