Disable git safe.directory in deployment image
I could not provision the environment due to:
== Installing/updating scap == ERROR: Specified source path "/srv/services/scap" does not seem to be a scap repository. Aborting bash: scap: command not found
The issue arises cause running as scap-deploy, git is unable to read
the config of the repositories under /srv/services. They are owned by
root and git recently learned to stop processing config files when
their owner mismatch the invoking user.
Add safe.directory = '*' to the global git configuration, to disable
the check entirely.
