vhost: add vhost interface add/delete/dump API test cases to make test

The vhost binary APIs for add/delete/dump interface were available long ago. But no unit tests were ever added in make test. This patch is to retrofit the missing unit tests. Change-Id: I489521b5ae359a1168ac5880a1f13a5f7e93ce4a Signed-off-by: Steven <sluong@cisco.com>
