safe.directory: setting safe.directory="." allows the "current" directory

When "git daemon" enters a repository, it chdir's to the requested repository and then uses "." (the curent directory) to consult the "is this repository considered safe?" when it is not owned by the same owner as the process. Make sure this access will be allowed by setting safe.directory to ".", as that was once advertised on the list as a valid workaround to the overly tight safe.directory settings introduced by 2.45.1 (cf. <834862fd-b579-438a-b9b3-5246bf27ce8a@gmail.com>). Also add simlar test to show what happens in the same setting if the safe.directory is set to "*" instead of "."; in short, "." is a bit tighter (as it is custom designed for git-daemon situation) than "anything goes" settings given by "*".
