cmd: check/add git safe.directory setting for every report access
This will hopefully address issues where reports were being silently skipped because of "unsafe" permissions. It's a bit harsh, but I don't know of any better option.
Setting "safe.directory = *" also gets around this issue, which is what I have done in all relevant accounts.
A second commit also bumps up report skip log message to a warning, to hopefully make it more obvious when reports are being skipped.
