Use ? for matching spaces
Use ? for matching spaces

Technically this isn't *quite* right as 'CentOSyStream' would also
match, but it's pretty reasonable:

- OS grains shouldn't ever be that kind of close
- This test is only swapping out spaces, and only for the os grain. That
  would mean there would have to be two OSes with grains that only
  differ by one having a space where another one has any other
  character.
- This test really isn't even about matching grains, we're just using
  compound matching and that's a reasonable one to use.
