Perform initial startup of virtualbmc

In latest version of virtualbmc (1.4.0) the way of
executing vbmc commands changed - during first command execution
vbmc spawns itself and binds to default port 50891. After this
normal operations can be performed. The patch also has been
tested on older version (1.3.0) successfully
