Remove nagios sudo
Replace root with current user and keep etc dir

Neither the opscode-nagios-cmd user nor the opscode-nagios user will exist at
build time.  Change them to the current user.

The nagios etc directory is emptied post install.  Add a .gitkeep to preserve
the path during a rebuild.
Add .gitkeep for embedded/logs

This is where nginx places the error log and pid file.
