RFR: JDK-8218177: Bump jib format_version to support new devkit archive layout

[Erik Joelsson]

This patch was a bit premature, but now with a proper fix in Jib, here 
is an updated version. It restores the use of the new devkit as well as 
changes some more instances of install_path to home_path.
