Steps to Reproduce

1. setup.sh
--machine xilinx-zynqmp --dl-layers  --distro wrlinux --templates feature/xfce feature/LAMP feature/aws feature/azure feature/grpc feature/ipv6 feature/krb5 feature/libvirt feature/lttng feature/mariadb feature/nfsd feature/ntp feature/opencv feature/package-management feature/pam-faillock feature/python-tkinter feature/software-entropy feature/sysklogd feature/system-stats feature/target-toolchain feature/tcpslice feature/usrmerge feature/virt-host feature/xfce --layers meta-filesystems meta-iot-cloud meta-security-compliance meta-virtualization --dl-layers --accept-eula=yes

2. source environment-setup-<host>-wrlinuxsdk-linux
   source oe-init-build-env
3. modify local.conf
    IMAGE_INSTALL:append = " rng-tools"

4. bitbake wrlinux-image-std 

5. boot target and run "systemctl status rng-tools.service"
