Recent git releases containing [1] have an ownership check when opening repositories, and refuse to open a repository if it is owned by a different user. This breaks any use of git in do_install, as that is executed by the (fake) root user. Whilst not common, this does happen. Setting the git configuration safe.directories=* disables this check, so that git is usable in fakeroot tasks. This can be set globally via the internal environment variable GIT_CONFIG_PARAMETERS, we can't use GIT_CONFIG_*_KEY/VALUE as that isn't present in all the releases which have the ownership check. We already set GIT_CEILING_DIRECTORIES to ensure that git doesn't recurse up out of the work directory, so this isn't a security issue.
