factory_install: Get mini-omaha addreess from tftp server.
This is for dymaic mini-omaha server address assignment.
Factory install shim gets tftp url from kernel command line.
Next, it gets omahaserver.conf from tftp server to override
mini-omaha server address. Then start factory installation.
This change considers backward compatibility. It works well
if there is no omahaserver.conf in tftp server.
BUG=chrome-os-partner:22180
TEST=Network boot and install on Falco.
