three changes for the configuration.
1、args [ "sh" ]: this is an example parameter and when the VM is started,
the parameter will be replaced by the launch_UOS script.
2、The linux capabilities will guarantee the Acrn-dm have enough capabilities
to run in container. For more infomation about the capalility you can refer
http://man7.org/linux/man-pages/man7/capabilities.7.htm
3、Move the rootfs to the parent directory, so all the container can share
the same rootfs.

Current launch script leaves stdio to OVMF console and, vxworks console to pty, so users
need to use additional tool like minicom to connect to pty device to use vxWorks.
To be more convinient, this commit changes the vxWorks to use the stdio by default, and OVMF
is not availabe by default.

When virtio-console is used as console port with socket backend,
guest kernel tries to hook it up with hvc console and sets it up.
It doesn't check if a client is connected and can result in ENOTCONN
with virtio-console backend being reset. This will prevent client
connection at a later point. To avoid this, ignore ENOTCONN error.
PS: For Kata, the runtime first launches VM and then proxy which acts
as a client connects to this socket. If this error is not handled,
proxy will never be able to connect as the backend itself will be reset.
