Set systemd as entrypoint.

2. I build an image extend sysbox here is dockerfile and named testdotnet
   FROM sysbox

RUN wget https://packages.microsoft.com/config/ubuntu/21.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
RUN dpkg -i packages-microsoft-prod.deb
RUN rm -rf packages-microsoft-prod.deb

RUN sudo apt-get update && \
sudo apt-get install -y apt-transport-https &&
sudo apt-get update &&
sudo apt-get install -y dotnet-sdk-6.0

ENV HOME=/home/admin
ENV DOTNET_ROOT=$HOME/dotnet
ENV PATH=$HOME/dotnet:$PATH
ENV PATH=$HOME/.dotnet/tools:$PATH
ENV DOTNET_CLI_TELEMETRY_OPTOUT=false

3. after I excutetd “sudo docker run --runtime=sysbox-runc -it --rm -P --hostname=syscont test” and ssh in the container testdotnet
4. I excuted dotnet new console -o myapp and cd myapp
5. when I excuted dotnet build in myapp，it show these message
   ，but if I run the cmd like this “sudo docker run -d -p 8080:80 testdotnet" it wouldn't appear this error
