git-daemon doesn't work as expected in v2.45.1 and friends

Hi,

during testing the newest security releases in RHEL and in Fedora, we have encountered broken git-daemon behavior. In a nutshell, git client refuses to clone locally hosted repositories because of detected dubious ownership.

I'll paste part of the Fedora report [0] here:

``` Upon clone, git-daemon logs the following:

    [1482] Connection from ::1:45090
    [1482] Extended attribute "host": localhost
    [1482] Extended attribute "protocol": version=2
    [1482] Request upload-pack for '/test.git'
    fatal: detected dubious ownership in repository at '/var/lib/git/test.git'
    To add an exception for this directory, call:
            git config --global --add safe.directory /var/lib/git/test.git

Reproducible: Always

Steps to Reproduce:
1. Create repository under /var/lib/git/test.git
2. Ensure git.socket systemd unit is started
3. Run git clone git://localhost/test.git
Actual Results:
git server refuses to read /var/lib/git/site.git because it detects dubious
ownership
```

Is there a way to make git-daemon hosted repositories safe to clone, without specifying safe.directory in git config? AFAIK this is widely used feature of Git not only by the end users, but also quite a lot of tests rely on it.
