VPP-574: fix VPP hang during security group configuration on a suspended VM

The unix connect() in vhost-user driver in VPP is blocking, and
a non-expedient accept() on the other side causes the entire VPP to hang.

Solution: set the nonblocking flag for the socket fd before calling
connect(), and set the socket back to blocking after the accept() succeeds.
