Updates to the safe.directory config option

Here is a very fast response to the security release yesterday.

The second patch here is an adaptation from a contributor who created a pull request against git/git [1]. I augmented the patch with a test (the test infrastructure is added in patch 1).

The third patch is a change to the safe.directory config option to include a possible "*" value to completely opt-out of the check. This will be particularly helpful for cases where users run Git commands within a container. This container workflow always runs as a different user than the host, but also the container does not have access to the host's system or global config files. It's also helpful for users who don't want to set the config for a large number of shared repositories [2].

Thanks, -Stolee
