RFC patcht7508-status: fix a bogus check in a submodule-related test

Since 90e14525f2 (Add tests for the diff.ignoreSubmodules config option, 2010-08-06) the test '.gitmodules ignore=dirty suppresses submodules with untracked content' in 't7508-status.sh' contains a check that is bogus for two reasons.

The commit in question added the following three lines at the beginning of that test:

  git config diff.ignoreSubmodules dirty &&
  git status >output &&
  ! test -s actual &&

That 'test' is problematic, because:

  - The output of 'git status' is saved in the file 'output', but the
    subsequent 'test' looks at the file 'actual'.  This is the first
    mention of 'actual' in t7508, so that file doesn't exist at that
    point, and, consequently, the 'test' itself fails.  However, since
    there is a '!' in front to flip the exit code, the command as a
    whole succeeds.
    I guess that this 'test' should look at the file 'output' instead,
    but...

  - This whole command checks that the given file is empty, i.e. that,
    supposedly, 'git status' produced no output.  However, in this
    case 'git status' does produce output, and indeed it should
    produce the same output as already expected in the neighbouring
    tests or even later in the same test, all running 'git status' in
    similar situations.

So drop that bogus check, and verify that 'git status's output matches what's otherwise expected in similar cases.

This is a submodules-related test, and I'm not very well versed in submodules, hence the RFC.
