Including git commands in preseed

[Todd Maurice <toddmaurice@outlook.com>]

I'm working on i386, Debian testing net install, in VirtualBox, through "auto url=""project" meaning clone command was not successful.

d-i preseed/late_command string apt-get update && apt-get dist-upgrade -y
d-i preseed/late_command string in-target git clone https://github.com/project

I would rather use preseed than a script.

Thanks for the help.
