Relocate the nbroot to /opt/xcat/share/netboot

-Override init with our own in order to preserve control of PID 1 (for switch_root)
-Change nbroot shell to actually call shell and loop, rather than exit since that would be init trying to exit now
-Increase destiny retrieval interval a bit to be less harsh, don't background as this must continue to be PID 1
