t7508: demonstrate status's failure to use --porcelain format with -z

When 'git status' is supplied the -z switch, and no output format has been
selected, it is supposed to use the --porcelain format.  This does not
happen.  Instead, the standard long format is used.  Add a test to
demonstrate this failure.
