minikube: set libvirt to LD_LIBRARY_PATH to avoid 'Failed to open libvirt.so.0' error

Currently `minikube start --driver=kvm2` fails with the following
message:

  Exiting due to GUEST_PROVISION: error provisioning guest: Failed to start host: recreate: creating host: create: creating: creating network: failed opening libvirt connection: failed connecting to libvirt socket: virError(Code=1, Domain=0, Message='Failed to open libvirt.so.0')

This commit fixes this problem by adding libvirt to LD_LIBRARY_PATH.
