[checkfs] prettify output

[diver]

Current checkfs output looks like this:

checked 7712 nodes, 0 blocks not allocated, 0 blocks already set, 0 blocks could be freed
         files           6545
         directories     1160
         attributes      1
         attr. dirs      1
         indices         5

But maybe it would be better with something like this?

	 checked 7712 nodes, 
	 0 blocks not allocated, 
	 0 blocks already set, 
	 0 blocks could be freed

         files         6545
         directories   1160
         attributes    1
         attr. dirs    1
         indices       5

I like the current version better, but maybe having all numbers in one row would improve the situation.

This should do the trick.
