Unclear from documentation whether init.sh and other scripts should be run as root #10

Hello. Thanks for making this important patch set. It's unclear from the documentation whether init.sh, build_runtime.sh etc should be run as root or not. It clearly states in README.md that install_tools.sh should be run as root. If I proceed to run init.sh as a normal user, I get the following error from kldload, which requires root privileges to run: 

aj@dotnet:~/dotnet-core-freebsd-source-build % sudo ./install_tools.sh

Running init.sh as root unsurprisingly solves the problem, but it means code is checked out as root, which is suboptimal for compiling the code itself (root shouldn't be required for this step). See below:

Hi, Yes this needs some more refactor, but in general those are put in there so I don't forget them on clean system :) The commands like mount and kldload and service linux start are one-time-needed and can be run by hand as root user - I just keep them around when doing new build/releases
