t0033-safe-directory: check when 'safe.directory' is ignored
According to the documentation 'safe.directory' "is only respected
when specified in a system or global config, not when it is specified
in a repository config or via the command line option -c
safe.directory=<path>".
Add tests to check that 'safe.directory' in the repository config or
on the command line is indeed ignored.
