Add bootstrap-sel.sh and selrc

Set up some housekeeping to run on every domain start.  Only do the minimal
still for a usable SEL environment
* install additional packages
* install the current /etc/selrc
  * Include work-around for microsoft/WSL#4189
  * set hostname to WSL distro name
  * run /etc/rc.local
