qemu-sockets: include strerror or gai_strerror output in error messages

Among others, before:

    $ qemu-system-x86_64 -chardev socket,port=12345,id=char
    inet_connect: host and/or port not specified
    chardev: opening backend "socket" failed

After:

    $ x86_64-softmmu/qemu-system-x86_64 -chardev socket,port=12345,id=char
    qemu-system-x86_64: -chardev socket,port=12345,id=char: host and/or port not specified
    chardev: opening backend "socket" failed

perror and fprintf can be removed because all clients can now
consume Errors properly.
