sd-journal: remove the dead code and actually fix #14695
    
    journal_file_fstat() returns an error if we call it on already unlinked
    journal file and hence we never reach remove_file_real() which is the
    entire point.
    
    I must have made some mistake while testing the fix that got me thinking
    the issue is gone while opposite was true.
    
    Fixes #14695
