sockets: Fix socket_sockaddr_to_address_unix() for abstract sockets
Commit 776b97d360 "qemu-sockets: add abstract UNIX domain socket
support" neglected to update socket_sockaddr_to_address_unix(). The
function returns a non-abstract socket address for abstract
sockets (wrong) with a null @path (also wrong; a non-optional QAPI str
member must never be null).
The null @path is due to confused code going back all the way to
commit 17c55decec "sockets: add helpers for creating SocketAddress
from a socket".
Add the required special case, and simplify the confused code.
Fixes: 776b97d3605ed0fc94443048fdf988c7725e38a9
