mdcheck: be careful when sourcing the output of "mdadm --detail --export" 

The output of "mdadm --detail --export" isn't quoted properly so
fields that contain spaces can be a problem.
We only want the MD_UUID field, and it has a very well defined
format with no spaces.
So use 'grep' to limit the output to just that.
