merd: Switch to AF_UNIX for qemu tap, provide wrapper

We can bypass a full-fledged network interface between qemu and merd by
connecting the qemu tap file descriptor to a provided UNIX domain
socket: this could be implemented in qemu eventually, qrap covers this
meanwhile.

This also avoids the need for the AF_PACKET socket towards the guest.
