Vagrantfile: Add test_ovs_system_userspace provision.
Add 'test_ovs_system_userspace' provision. Command:
# vagrant provision --provision-with=test_ovs_system_userspace
will run "make check-system-userspace" in the vagrant launched VM.
It may be more convenient to run this tests inside a vm rather than in
the host, because they interact with system networking.
