Fix image build to override root homedir in /etc/passwd (ansible#1027) (

ansible#1062)

* override root homedir in /etc/passwd

* using only `HOME` envvar to override homedir causes mismatches with anything that asks for it a different way (eg, `echo ~root`)
* kicking the can down the road on "why are we overriding /root as root's homedir anyway?"

* more dynamic homedir handling

* just make everybody's home /home/runner

* restore ENV HOME override for builds

* comment wording
