selinux: implement the security_uring_cmd() LSM hook
Add a SELinux access control for the iouring IORING_OP_URING_CMD
command. This includes the addition of a new permission in the
existing "io_uring" object class: "cmd". The subject of the new
permission check is the domain of the process requesting access, the
object is the open file which points to the device/file that is the
target of the IORING_OP_URING_CMD operation. A sample policy rule
is shown below:
allow <domain> <file>:io_uring { cmd };
