statprof: fix off-by-one-line error in output
martinvonz claims they thought that this was intentional, but couldn't remember
the reasoning for it. I can't understand why it would be preferable, and I
didn't see anything in the comments in the file about why this would be useful,
so I'm hopefully not breaking anything by "fixing" it.
