Compatibility fixes with Ubuntu 18.04
Currently we are using ip:port socket to for VPP to listen for incoming connections. There is only one place in code this socket is used for detection if VPP is responding after restart. This patch is supposed to change ip:port to sock:file which is default preffered way in VPP. This way we can start using vppctl. netcat on the other side with ip:port remains hanged in console for infinite time not returning back. There is also need to check whether uio_module is loaded and eventually load it. As uio_pci_generic is not working there, we will fallback to main igb_uio (uio_pci_generic being only lightweight subset of igb_uio). This patch also add additional verbose output to console during setup to better understand if failure happens during copy/extract/setup.
