Starting from Linux 5.6, VMADDR_CID_LOCAL is supported to do local communication (loopback device).

Before Linux 5.6 it was called VMADDR_CID_RESERVED and was not supported, so we could expect an EADDRNOTAVAIL, but now this address is supported and handled by the 'vsock_loopback' kernel module loaded automatically if no other vsock transports are loaded.

This reverts commit c0783e7.

Now the test should work correctly, so we can re-enable it.

1407: Fix test_vsock failure on VMADDR_CID_LOCAL testing and re-enable it r=asomers a=stefano-garzarella

Starting from Linux 5.6, `VMADDR_CID_LOCAL` is supported to do local communication (loopback device).

Before Linux 5.6 it was called `VMADDR_CID_RESERVED` and was not supported, so we could expect an `EADDRNOTAVAIL`, but now this address is supported and handled by the 'vsock_loopback' kernel module loaded automatically if no other vsock transports are loaded.
